In June 2023, we sold approximately 192 acres of real estate at WE's former Pleasant Prairie power plant site that was no longer being utilized in its operations, for $23.0 million, which is net of closing costs. As a result of the sale, a pre-tax gain in the amount of $22.2 million was recorded within other operation and maintenance expense on our income statement. The book value of the real estate included in the sale was not material and, therefore, was not presented as held for sale.

Sale of Certain Real Estate by The Peoples Gas Light and Coke Company

In May 2022, we sold approximately 11 acres of real estate owned by PGL that was no longer being utilized in its operations, for $55.1 million.million, which is net of closing costs. The real estate was located in Chicago, Illinois. As a result of the sale, a pre-tax gain in the amount of $54.5 million was recorded within other operation and maintenance expense on our income statement. The book value of the real estate included in the sale was not material and, therefore, was not presented as held for sale.

Disaggregation of Operating Revenues

The following tables present our operating revenues disaggregated by revenue source. We do not have any revenues associated with our electric transmission segment, which includes investments accounted for using the equity method. We disaggregate revenues into categories that depict how the nature, amount, timing, and uncertainty of revenues and cash flows are affected by economic factors. For our segments, revenues are further disaggregated by electric and natural gas operations and then by customer class. Each customer class within our electric and natural gas operations havehas different expectations of service, energy and demand requirements, and can be impacted differently by regulatory activities within their jurisdictions.

(1)Includes the revenues subject to the purchased gas recovery mechanisms of our utilities. The amounts for the three months ended June 30, 2022 reflect higherutilities, which fluctuate by segment based on actual natural gas costs incurred than were anticipated in rates. Duringat our utilities, compared with the six months ended June 30, 2022, we continued to recover natural gas costs we under-collected from our customers in 2021, related to the extreme weather. As these amounts were billed to customers, they were reflected in retail revenues with an offsetting decrease in other utility revenues. The negative amount during this period also relates to the over-collectionrecovery of natural gas costs recorded in a regulatory liability due to these costs being lower than what was anticipated in rates. See Note 6, Regulatory Assets and Liabilities, for more information.

The negative amount for the three months ended June 30, 2021 primarily relates to the approval by our utility commissions to recover from customers, over the second quarter of 2021, the higher natural gas costs that were incurred as a result of the extreme winter weather conditionsanticipated in February 2021. As these amounts were billed to customers, they were reflected in retail revenues with an offsetting decrease in other utility revenues. For the six months ended June 30, 2021, in addition to costs related to the extreme weather event, we incurred higher natural gas costs as a result of an increase in the price of natural gas.rates.

See Note 23, Regulatory Environment, for more information.

Other Natural Gas Operating Revenues

We have other natural gas operating revenues from Bluewater, which is in our non-utility energy infrastructure segment. Bluewater has entered into long-term service agreements for natural gas storage services with WE, WPS, and WG, and also provides limited service to unaffiliated customers. All amounts associated with the service agreements with WE, WPS, and WG have been eliminated at the consolidated level.

NOTE 5—CREDIT LOSSES

Our exposure to credit losses is related to our accounts receivable and unbilled revenue balances, which are primarily generated from the sale of electricity and natural gas by our regulated utility operations. Credit losses associated with our utility operations are analyzed at the reportable segment level as we believe contract terms, political and economic risks, and the regulatory environment are similar at this level as our reportable segments are generally based on the geographic location of the underlying utility operations.

We have an accounts receivable and unbilled revenue balance associated with our non-utility energy infrastructure segment, related to the sale of electricity from our majority-owned windrenewable generating facilities through agreements with several large high credit quality counterparties.

We evaluate the collectability of our accounts receivable and unbilled revenue balances considering a combination of factors. For some of our larger customers and also in circumstances where we become aware of a specific customer's inability to meet its financial obligations to us, we record a specific allowance for credit losses against amounts due in order to reduce the net recognized receivable to the amount we reasonably believe will be collected. For all other customers, we use the accounts receivable aging method to calculate an allowance for credit losses. Using this method, we classify accounts receivable into different aging buckets and calculate a reserve percentage for each aging bucket based upon historical loss rates. The calculated reserve percentages are updated on at least an annual basis, in order to ensure recent macroeconomic, political, and regulatory trends are captured in the calculation, to the extent possible. Risks identified that we do not believe are reflected in the calculated reserve percentages, are assessed on a quarterly basis to determine whether further adjustments are required.

We monitor our ongoing credit exposure through active review of counterparty accounts receivable balances against contract terms and due dates. Our activities include timely account reconciliation, dispute resolution and payment confirmation. To the extent possible, we work with customers with past due balances to negotiate payment plans, but will disconnect customers for non-payment as allowed by our regulators, if necessary, and employ collection agencies and legal counsel to pursue recovery of defaulted receivables. For our larger customers, detailed credit review procedures may be performed in advance of any sales being

(1)Our exposure to credit losses for certain regulated utility customers is mitigated by regulatory mechanisms we have in place. Specifically, rates related to all of the customers in our Illinois segment, as well as the residential rates of WE, WPS, and WG in our Wisconsin segment, include riders or other mechanisms for cost recovery or refund of uncollectible expense based on the difference between the actual provision for credit losses and the amounts recovered in rates. As a result, at June 30, 2022, $782.22023, $767.6 million, or 54.0%58.4%, of our net accounts receivable and unbilled revenues balance had regulatory protections in place to mitigate the exposure to credit losses.

A rollforward ofOn a consolidated basis, there was a $20.6 million decrease in the allowance for credit losses at June 30, 2023, compared to January 1, 2023, driven by reportable segmentcustomer write-offs related to the winter moratorium months ending. After a customer is included below:disconnected for a period of time without payment on their account, we will write off that customer balance. In Wisconsin, the winter moratorium begins on November 1 and ends on April 15, and in Illinois the winter moratorium begins on December 1 and ends on March 31. Also contributing to the decrease in the allowance for credit losses, we believe that the lower energy costs that customers were seeing, which were driven by lower natural gas prices, contributed to a reduction in past due accounts receivable balances and a related decrease in the allowance for credit losses.

On a consolidated basis, there was a $22.5 million decrease in the allowance for credit losses at June 30, 2022, compared to December 31, 2021.January 1, 2022. The decrease was driven by customer write-offs related to collection practices returning to pre-pandemic levels in 2021, including the restoration of our ability to disconnect customers. After a customer is disconnected for a period of time without payment on their account, we will write off that customer balance. Partially offsetting the decrease in the allowance for credit losses, we believe that the high energy costs that customers arewere seeing, which have beenwere driven by high natural gas prices, contributed to higher past due accounts receivable balances and a related increase in the allowance for credit losses.

The increase in the allowance for credit losses at June 30, 2021, compared to December 31, 2020, was driven by higher past due accounts receivable balances related to our utility operations, primarily associated with our residential customers. This increase in accounts receivable balances in arrears related to the continued economic disruptions caused by the COVID-19 pandemic, including high unemployment rates. However, as seen in the quarterly rollforward above, the allowance for credit losses began to decrease in the second quarter of 2021, which we believe was related to the start of normal collection practices in our Wisconsin and Illinois service territories.

(3)    The decrease in these regulatory liability balances was primarily related to the PSCW's approval of certain accounting treatments that allowed our Wisconsin utilities to forego applying for a 2022 base rate increase, and instead maintain base rates consistent with 2021 levels. Among the accounting treatments approved was the amortization of certain regulatory liability balances in 2022, to offset a portion of the forecasted revenue deficiency.

NOTE 7—PROPERTY, PLANT, AND EQUIPMENT

Wisconsin Segment Plant to be Retired

Oak Creek Power Plant Units 5 – 8

As a result of a PSCW approval for the construction of a solar and battery project received in December 2022, retirement of the OCPP generating units 5 – 8 became probable. In early 2023, we received additional approvals for electric generation facilities, including West Riverside and Koshkonong. See Note 2, Acquisitions, for more information on the acquisition of West Riverside, which was completed in June 2023. OCPP units 5 and 6 are expected to be retired by May 2024, while units 7 and 8 are expected to be retired by late 2025. The total net book value of WE's ownership share of units 5 – 8 was $808.1 million at June 30, 2023, which does not include deferred taxes. This amount was classified as plant to be retired within property, plant, and equipment on our balance sheet. These units are included in rate base, and WE continues to depreciate them on a straight-line basis using the composite depreciation rates approved by the PSCW.

Columbia Units 1 and 2

As a result of a MISO ruling received in June 2021, retirement of the jointly-owned Columbia generating units 1 and 2 became probable. Columbia generating units 1 and 2 are expected to be retired by June 1, 2026. The retirement date for these plants was pushed back from the end of 2023 for unit 1 and the end of 2024 for unit 2. See Note 23, Regulatory Environment, for more information on the Columbia generating units' retirement. Thetotal net book value of WPS's ownership share of unitunits 1 and unit 2 was $86.6$264.3 million and $185.6 million, respectively, at June 30, 2022. These amounts were2023, which does not include deferred taxes. This amount was classified as plant to be retired within property, plant, and equipment on our balance sheets.sheet.

Public Service Building and Steam Tunnel AssetsSamson I Solar Energy Center LLC Storm Damage

During a significant rain eventwind storm in May 2020, an underground steam tunnel in downtown Milwaukee flooded and steam vented into WE’s PSB. The damage to the building and adjacent steam tunnel assets from the flooding and steam was extensive and required significant repairs and restorations.March 2023, certain sections across approximately 40% of our Samson I solar facility incurred some amount of damage. As of June 30, 2022, WE had incurred $95.32023, we recognized an impairment of $1.6 million of costs related to these repairs and restorations. In 2020, WE received $20.0damage from this storm, which was offset by a $1.6 million ofreceivable for future insurance proceeds to cover a portion of these costs and wrote off $12.5 million of costs that we do not intend to seek recovery for through other operation and maintenance expense. Inrecoveries. The impairment initially recorded in the first quarter of 2022, WE received $41.0 million2023 was reduced after we updated our damage assessment in the second quarter. Although we may experience differences between periods in the timing of insurance proceeds as a result of a settlement that was reached in February 2022. The remaining $21.8 million of costs is expected to be recovered through rates.

In June 2021, we received approval from the PSCW to restore the PSB and adjacent steam tunnel assets and to defer the project costs, net of insurance proceeds, as a component of rate base. As such, and in light of the agreement with insurers noted above,cash flows, we do not currently expect a significant impact to our future results of operations.long-term cash flows from this event.

NOTE 8—JOINTLY OWNED UTILITY FACILITIES

We hold joint ownership interests in certain electric generating facilities. We are entitled to our share of generating capability and output of each facility equal to our respective ownership interest. We pay our ownership share of additional construction costs and have supplied our own financing for all jointly owned projects. We record our proportionate share of significant jointly owned electric generating facilities as property, plant, and equipment on the balance sheets. In addition, our proportionate share of direct expenses for the joint operation of these plants is recorded within operating expenses in the income statements.

In April 2023, WPS, along with an unaffiliated utility, completed the acquisition of Red Barn, a commercially operational utility-scale wind-powered electric generating facility. WPS owns 90%, or 82 MWs, of Red Barn.

In June 2023, WE completed the acquisition of a 13.8% ownership interest, or 100 MWs, of West Riverside, a commercially operational dual fueled combined cycle generation facility.

NOTE 11—LONG-TERM DEBT

In March 2022, President Biden signed into law the Adjustable Interest Rate (LIBOR) Act. This Act established a uniform process, on a nationwide basis, for replacing LIBOR in certain contracts that did not provide a clearly defined or practicable replacement benchmark rate. Under the LIBOR Act, the Federal Reserve Board was required to determine an appropriate benchmark replacement based on SOFR, with applicable credit spread adjustments. In December 2022, the Federal Reserve Board adopted the final rule to implement the LIBOR Act and established the SOFR-based benchmark replacements. No contract modifications are required for qualifying contracts under the LIBOR Act as the benchmark replacement automatically overrides the existing contract language and becomes the applicable benchmark after June 30, 2023.

For our $500.0 million 2007 Junior Notes, the benchmark replacement rate will be the applicable tenor of three-month CME Term SOFR, as administered by the CME Group Benchmark Administration, and will include a credit spread adjustment of 0.26161% per annum starting August 15, 2023. In accordance with the LIBOR Act, no contract modifications were required for our 2007 Junior Notes as the references to LIBOR were replaced by operation of law.

NOTE 10—12—LEASES

Obligations Under Finance Leases

Land Leases – Utility Solar Generation

WE and WPS have partnered with an unaffiliated utility to acquire and construct Darien, aParis, a utility-scale solar-powered electric generating facility with a battery energy storage system in Kenosha County,Rock and Walworth counties, Wisconsin. WE and WPS own 75% and 15%, respectively, of Paris. Once fully constructed, WE and WPS will collectively own 180 MWDarien. Commercial operation of solar generation and 99 MW of battery storage of this project. The PSCW has approved the acquisition and construction of Paris, and commercial operation for the solar portion of the project is targeted in 2023.2024.

Related to their investment in Paris,Darien, WE and WPS, along with their unaffiliated utility partner, entered into several land leases in Kenosha County, Wisconsin that commenced in the second quarter of 2022.2023. Each lease has an initial construction term that ends upon achieving commercial operation, then automatically extends for 25 years with an option for an additional 25-year extension.
06/30/2022 Form 10-Q20WEC Energy Group, Inc.


Table of Contents
We expect the optional extension to be exercised, and, as a result, the land leases are being amortized over the extended term of the leases. Once Darien achieves commercial operation, the lease liability will be remeasured to reflect the final total acres being leased. The lease payments will be recovered through rates.

Our total obligation under the land-related finance leases for ParisDarien was approximately $52.5$39.7 million at June 30, 2022,2023, and will decrease to zero over the remaining lives of the leases. Long-term lease liabilities related to our finance land leases for Paris werewas included in long-term debt on theour balance sheet. Our finance lease right of use asset related to ParisDarien was $52.5$39.4 million as of June 30, 2022,2023, and was included in property, plant, and equipment on our balance sheet.

In accordance with Accounting Standards Codification Subtopic 980-842, Regulated Operations – Leases (Subtopic 980-842), the expense recognition pattern associated with Paristhe Darien leases resembles that of an operating lease, as amortization of the right of use assets has been modified from what would typically be recorded for a finance lease under Topic 842.lease. The difference between the minimum lease payments and the sum of imputed interest and unadjusted amortization costs calculated under Topic 842 is deferred as a regulatory asset on our balance sheet in accordance with Subtopic 980-842 on our balance sheet.980-842.

At June 30, 2022,2023, our weighted-average discount rate for the ParisDarien finance leases was 5.28%5.96%. We used the fully collateralized incremental borrowing rates based upon information available for similarly rated companies in determining the present value of lease payments.

Future minimum lease payments and the corresponding present value of our net minimum lease payments under the finance leases for ParisDarien as of June 30, 2022,2023, were as follows:

PGL and NSG price natural gas storage injections at the calendar year average of the costs of natural gas supply purchased. Withdrawals from storage are priced on the LIFO cost method. For interim periods, the difference between current projected replacement cost and the LIFO cost for quantities of natural gas temporarily withdrawn from storage is recorded as a temporary LIFO liquidation debit or credit. At June 30, 2022,2023, we had a temporary LIFO liquidation credit of $107.6$2.1 million recorded within other current liabilities on our balance sheet. Due to seasonality requirements, PGL and NSG expect these interim reductions in LIFO layers to be replenished by year end.

Substantially all other materials and supplies, natural gas in storage, materials and supplies, and fossil fuel inventories are recorded using the weighted-average cost method of accounting.

The effective tax rates of 18.1% and 18.2% for the three and six months ended June 30, 2023, and 2022, respectively, differ from the United States statutory federal income tax rate of 21%, primarily due to PTCs generated from ownership interests in windrenewable generation facilities in our non-utility energy infrastructure segmentand Wisconsin segments and the impact of the protected deferred tax benefits associated with the Tax Legislation, as discussed in more detail below. These items were partially offset by state income taxes.

The effective tax rates of 16.4% and 14.1% for the three and six months ended June 30, 2021, respectively, differ from the United States statutory federal income tax rate of 21%, primarily due to PTCs generated from ownership interests in wind generation facilities in our non-utility energy infrastructure segment and the recognition of certain unprotected deferred tax benefits created as a result of the Tax Legislation. Effective January 1, 2020, in accordance with the rate order received from the PSCW in December 2019, our Wisconsin utilities began amortizing the unprotected deferred tax benefits over periods ranging from two years to four years, to reduce near-term rate impacts to their customers. In addition, the impact of the protected deferred tax benefits associated with the Tax Legislation, as discussed in more detail below, drove a decrease in the effective tax rate. These items were partially offset by state income taxes.

The Tax Legislation required our regulated utilities to remeasure their deferred income taxes and we began to amortize the resulting excess protected deferred income taxes beginning in 2018 in accordance with normalization requirements (see federal excess deferred tax amortization linelines above).

See Note 26, Regulatory Environment, in our 20212022 Annual Report on Form 10-K for additionalmore information on unprotected tax benefits.about the impact of the Tax Legislation.

NOTE 13—15—FAIR VALUE MEASUREMENTS

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price).

06/30/20222023 Form 10-Q2223WEC Energy Group, Inc.


Table of Contents
Fair value accounting rules provide a fair value hierarchy that prioritizes the inputs used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurement) and the lowest priority to unobservable inputs (Level 3 measurement). The three levels of the fair value hierarchy are defined as follows:

Level 1 – Quoted prices are available in active markets for identical assets or liabilities as of the reporting date. Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis.

Level 2 – Pricing inputs are observable, either directly or indirectly, but are not quoted prices included within Level 1. Level 2 includes those financial instruments that are valued using external inputs within models or other valuation methods.

Level 3 – Pricing inputs include significant inputs that are generally less observable from objective sources. These inputs may be used with internally developed methods that result in management's best estimate of fair value. Level 3 instruments include those that may be more structured or otherwise tailored to customers' needs.

Assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. We use a mid-market pricing convention (the mid-point price between bid and ask prices) as a practical measure for valuing certain derivative assets and liabilities. We primarily use a market approach for recurring fair value measurements and attempt to use valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs.

When possible, we base the valuations of our assets and liabilities on quoted prices for identical assets and liabilities in active markets. These valuations are classified in Level 1. The valuations of certain contracts not classified as Level 1 may be based on quoted market prices received from counterparties and/or observable inputs for similar instruments. Transactions valued using these inputs are classified in Level 2. Certain derivatives, such as FTRs and TCRs, are categorized in Level 3 due to the significance of unobservable or internally-developed inputs. Our derivative instruments categorized as Level 3 consisted of both FTRs and TCRs at June 30, 2022 and of only FTRs at December 31, 2021. These derivative instruments are valued using auction prices from the applicable regional transmission organization.

The following tables summarize our financial assets and liabilities that were accounted for at fair value on a recurring basis, categorized by level within the fair value hierarchy:

NOTE 14—16—DERIVATIVE INSTRUMENTS

We use derivatives as part of our risk management program to manage the risks associated with the price volatility of interest rates, purchased power, generation, and natural gas costs for the benefit of our customers and shareholders. Our approach is non-speculative and designed to mitigate risk. Regulated hedging programs are approved by our state regulators.

We record derivative instruments on our balance sheets as an asset or liability measured at fair value unless they qualify for the normal purchases and sales exception and are so designated. We continually assess our contracts designated as normal and will discontinue the treatment of these contracts as normal if the required criteria are no longer met. Changes in the derivative's fair value are recognized currently in earnings unless specific hedge accounting criteria are met or we receive regulatory treatment for the derivative. For most energy-related physical and financial contracts in our regulated operations that qualify as derivatives, our regulators allow the effects of fair value accounting to be offset to regulatory assets and liabilities.

Cash Flow Hedges

Until their expiration on November 15, 2021, we had 2 interest rate swaps with a combined notional value of $250.0 million to hedge the variable interest rate risk associated with our 2007 Junior Notes. The swaps provided a fixed interest rate of 4.9765% on $250.0 million of the $500.0 million of outstanding 2007 Junior Notes. As these swaps qualified for cash flow hedge accounting treatment, the related gains and losses were deferred in accumulated other comprehensive loss and were amortized to interest expense as interest was accrued on the 2007 Junior Notes.

We previously entered into forward interest rate swap agreements to mitigate the interest rate exposure associated with the issuance of long-term debt related to the acquisition of Integrys. These swap agreements were settled in 2015, and we continue to amortize amounts out of accumulated other comprehensive loss into interest expense over the periods in which the interest costs are recognized in earnings.

The table below shows the amountsderivative gains related to these cash flow hedges that wereswap agreements reclassified from accumulated other comprehensive loss to interest expense along with our total interest expense on the income statements:

We pay ATC for network transmission and other related services it provides. In addition, we provide a variety of operational, maintenance, and project management work for ATC, which is reimbursed by ATC. We are also required to initially fund the construction of transmission infrastructure upgrades needed for new generation projects. ATC owns these transmission assets and reimburses us for these costs when the new generation is placed in service.

NOTE 20—22—VARIABLE INTEREST ENTITIES

The primary beneficiary of a VIE must consolidate the entity's assets and liabilities. In addition, certain disclosures are required for significant interest holders in VIEs.

We assess our relationships with potential VIEs, such as our coal suppliers, natural gas suppliers, coal transporters, natural gas transporters, and other counterparties related to PPAs, investments, and joint ventures. In making this assessment, we consider, along with other factors, the potential that our contracts or other arrangements provide subordinated financial support, the obligation to absorb the entity's losses, the right to receive residual returns of the entity, and the power to direct the activities that most significantly impact the entity's economic performance.

WEPCo Environmental Trust Finance I, LLC

In November 2020, the PSCW issued a financing order approving the securitization of $100 million of undepreciated environmental control costs related to WE's retired Pleasant Prairie power plant, the carrying costs accrued on the $100 million during the securitization process, and the related financing fees. The financing order also authorized WE to form WEPCo Environmental Trust, a bankruptcy-remote special purpose entity, for the sole purpose of issuing ETBs to recover the costs approved in the financing order. WEPCo Environmental Trust is a wholly-ownedwholly owned subsidiary of WE.

In May 2021, WEPCo Environmental Trust issued ETBs and used the proceeds to acquire environmental control property from WE. The environmental control property is recorded as a regulatory asset on our balance sheets and includes the right to impose, collect, and receive a non-bypassable environmental control charge from WE's retail electric distribution customers until the ETBs are paid in full and all financing costs have been recovered. The ETBs are secured by the environmental control property. Cash collections from the environmental control charge and funds on deposit in trust accounts are the sole sourcesources of funds to satisfy the debt obligation. The bondholders have no recourse to WE or any of WE's affiliates other than WEPCo Environmental Trust.affiliates.

WE acts as the servicer of the environmental control property on behalf of WEPCo Environmental Trust and is responsible for metering, calculating, billing, and collecting the environmental control charge. As necessary, WE is authorized to implement periodic adjustments of the environmental control charge. The adjustments are designed to ensure the timely payment of principal, interest, and other ongoing financing costs. WE remits all collections of the environmental control charge to an indenture trustee of WEPCo Environmental Trust.Trust's indenture trustee.

WEPCo Environmental Trust is a VIE primarily because its equity capitalization is insufficient to support its operations. As described above, WE has the power to direct the activities that most significantly impact WEPCo Environmental Trust's economic performance. Therefore, WE is considered the primary beneficiary of WEPCo Environmental Trust, and consolidation is required.

Investment in Transmission Affiliates

We own approximately 60% of ATC, a for-profit, electric transmission company regulated by the FERC and certain state regulatory commissions. We have determined that ATC is a VIE but consolidation is not required since we are not ATC's primary beneficiary. As a result of our limited voting rights, we do not have the power to direct the activities that most significantly impact ATC's economic performance. Therefore, we account for ATC as an equity method investment. At June 30, 20222023 and December 31, 2021,2022, our equity investment in ATC was $1,813.6$1,931.8 million and $1,766.9$1,884.6 million, respectively, which approximates our maximum exposure to loss as a result of our involvement with ATC.

We also own approximately 75% of ATC Holdco, a separate entity formed in December 2016 to invest in transmission-related projects outside of ATC's traditional footprint. We have determined that ATC Holdco is a VIE but consolidation is not required since we are not ATC Holdco's primary beneficiary. As a result of our limited voting rights, we do not have the power to direct the activities that most significantly impact ATC Holdco's economic performance. Therefore, we account for ATC Holdco as an equity method investment. At June 30, 20222023 and December 31, 2021,2022, our equity investment in ATC Holdco was $23.6$24.1 million and $22.5$24.6 million, respectively, which approximates our maximum exposure to loss as a result of our involvement with ATC Holdco.

See Note 18,20, Investment in Transmission Affiliates, for more information, including any significant assets and liabilities related to ATC and ATC Holdco recorded on our balance sheets.

Power Purchase Commitment

On May 31, 2022, WE's PPA with LSP-Whitewater Limited Partnership that represented a variable interest expired. This agreement was for 236.5 MWs of firm capacity from a natural gas-fired cogeneration facility, and we accounted for it as a finance lease.

In November 2021, WE entered into a tolling agreement with LSP-Whitewater Limited Partnership that commenced on June 1, 2022, upon the expiration of the PPA.

NOTE 21—23—COMMITMENTS AND CONTINGENCIES

We and our subsidiaries have significant commitments and contingencies arising from our operations, including those related to unconditional purchase obligations, environmental matters, and enforcement and litigation matters.

Unconditional Purchase Obligations

Our electric utilities have obligations to distribute and sell electricity to their customers, and our natural gas utilities have obligations to distribute and sell natural gas to their customers. The utilities expect to recover costs related to these obligations in future customer rates. In order to meet these obligations, we routinely enter into long-term purchase and sale commitments for various quantities and lengths of time.

The windrenewable generation facilities that are part of our non-utility energy infrastructure segment have obligations to distribute and sell electricity through long-term offtake agreements with their customers for all of the energy produced. In order to support these sales obligations, these companies enter into easements and other service agreements associated with the wind generating facilities.

Our minimum future commitments related to these purchase obligations as of June 30, 2022,2023, including those of our subsidiaries, were approximately $10.5$10.2 billion.

Environmental Matters

Consistent with other companies in the energy industry, we face significant ongoing environmental compliance and remediation obligations related to current and past operations. Specific environmental issues affecting us include, but are not limited to, current and future regulation of air emissions such as sulfur dioxide, NOx, fine particulates, mercury, and GHGs; water intake and discharges; management of coal combustion products such as fly ash; and remediation of impacted properties, including former manufactured gas plant sites.

Cross State Air Pollution Rule – Good Neighbor Plan

TheIn March 2023, the EPA issued a proposedits final Good Neighbor Plan, which requires significant reductions in ozone-forming emissions of NOx from power plants and industrial facilities. The rule that would update and expand the Cross-State Air Pollution Rule's ozone-season NOx program to address the 2015 ozone NAAQS, resulting in more stringent regulation of ozone-season NOx emissions from EGUs in 26 states, relying on authorization through the CAA's “good neighbor provision." As part of the proposed rule, expected towill take effect in MayAugust 2023, during the EPA would establish a new trading program that would impose lower NOx emissions budgets on states, at levels that the EPA projected would be achievable through full operation of existing EGU emissions control equipment beginning during ozone season 2023, and through installation of additional control equipment at both EGU and non-EGU stationary sources by the startlatter half of the 20262023 ozone season, as well as planned plant retirements.

After review of our existing units' 2020 and 2021 actual ozone season emissions and projected future emissions versus proposed NOx ozone season allocations,the final rule, we anticipatebelieve that we should be ableare well positioned to comply withmeet the expanded rule requirements without procuring additional allowances on the open market.requirements.

Our RICE units in the Upper Peninsula of Michigan and planned RICE units in Wisconsin are not currently subject to thisthe final rule as proposed as each unit is expected to be less than 25 MW. We note that, toMWs. To the extent we use RICE engines for natural gas distribution operations, those engines may be subject to the emission limits and operational requirements of the rule beginning in 2026. In June 2022, we submitted comments on this proposed rule seeking clarification of its applicability, as well as other items, and we will closely monitorThe EPA has exempted LDCs from the final rule for any changesbut included new language defining an LDC that we are still evaluating.

Mercury and Air Toxics Standards

In 2012, the EPA issued the MATS to limit emissions of mercury, acid gases, and other hazardous air pollutants. In April 2023, the EPA issued the pre-publication version of a proposed rule to strengthen and update MATS to reflect recent developments in control technologies and performance of coal and oil-fired units. The EPA proposed three revisions including a proposal to lower the PM limit from 0.03 lb/MMBtu to 0.01 lb/MMBtu, which could have an adverse effect on our utilities. The EPA is also seeking comments on an even lower limit of 0.006 lb/MMBtu. We submitted comments to the EPA in June 2023 addressing several concerning portions of the proposed rule.rule revisions.

Ozone

After completing its review of the 2008 ozone standard, the EPA released a final rule in October 2015, creating a more stringent standard than the 2008 NAAQS. The 2015 ozone standard lowered the 8-hour limit for ground-level ozone. In December 2020,November 2022, the EPA's 2022 CASAC Ozone Review Panel issued a draft report supporting a previously issued EPA completed its 5-year reviewstaff-written Integrated Science Assessment for ozone which supported the reconsideration of the ozone standard and2015 standard.

In April 2022, the EPA proposed to find that the Milwaukee and Chicago, IL-IN-WI nonattainment areas did not meet the marginal attainment deadline of August 2021 and willshould be adjusted to "moderate" nonattainment status for the 2015 standard. In October 2022, the EPA published its final reclassifications from "marginal" to "moderate" for these areas, effective November 7, 2022. Accordingly, Wisconsin must submit State Implementation Plan revisionsthe WDNR submitted a SIP revision to the EPA in December 2022 to address the reclassifications.

In February 2022, revisions to the Wisconsin Administrative Code to adopt the 2015 standard were finalized. The amended regulations adopted the standard and incorporated by reference the federal air pollution monitoring requirements related to the standard. We believe that we are well positioned to meet the requirements associated with the 2015 ozone standard and do not expect to incur significant costs to comply with the associated state and federal rules.

Particulate Matter

In December 2020, the EPA completed its 5-year review of the 2012 annual and 24-hour standards for fine particulate matter. The EPAPM and determined that no revisions were necessary to the current annual standard of 12 µg/m3 or the 24-hour standard of 35 µg/m3. This determination was also subject to review under Executive Order 13990 and in June 2021, the EPA announced it would reconsider the December 2020 decision. Under the Biden Administration's policy review, the EPA concluded that the scientific evidence and information from the December 2020 determination supports revising the level of the annual standard for the particulate matterPM NAAQS to below the current level of 12 µg/m3, while retaining the 24-hour standard. In March 2022, the EPA’s CASAC sent a letter toJanuary 2023, the EPA finalizingannounced its peer reviewproposed decision to revise the primary (health-based) annual PM2.5 standard from its current level of the particulate matter standards.

The EPA also proposed not to change the members ofcurrent secondary (welfare-based) annual PM2.5 standard, primary and secondary 24-hour PM2.5 standards, and primary and secondary PM10 standards.

Additionally, a majority of) included in the CASAC members favored lowering the 24-hour standard, while a minority concurred with EPA’s preliminary conclusion to retain the 24-hour standard without revision. In May 2022, the EPA released its staff-written Policy Assessment forCASAC's latest report. A final decision on the reconsideration of the standard. Similar to the CASAC findings, the EPA staff found that conditions supported either an annual standardis anticipated in the 10 to 12 µg/m3 range or in the 8 to 10 µg/m3 range.

A proposed rule is expected in August 2022, and a final rule is expected in springlate summer 2023. All counties within our service territories are in attainment with the current 2012 standards. If the EPA lowers the annual standard to 10 or 11 µg/m3, our generating facilities within our service territories should remain in attainment. If the EPA lowers it to below 10 µg/m3, there could be some non-attainmentnonattainment areas that may affect permitting of some smaller ancillary equipment located at our facilities. After finalization of the rule, the WDNR will need to draft and submit a SIP for the EPA's approval.

Climate Change

For coal plants, there are no applicable standards until 2032, and after 2032 the D.C. Circuit Court of Appealsapplicable standard is dependent on the unit's retirement date. For combined cycle natural gas plants above a 50% capacity factor, the rule is highly dependent on hydrogen as an alternative fuel, or carbon capture. For simple cycle natural gas-fired combustion turbines, there are no applicable limits as long as the capacity factor is less than 20%. Our RICE units in January 2021. In October 2021,Michigan and the Supreme Court agreed to reviewnew Weston RICE project are not affected under the D.C. Circuit Court's ruling vacatingrule because each RICE unit is less than 25 MWs. We are evaluating the EPA's ACE rule and in June 2022, the Supreme Court issued its decision. The Supreme Court found that the EPA may regulate GHGs under section 111 of the CAA but cannot rely on generation shifting to lower carbon emitting sources to do so. Based on an updated EPA regulatory timeline, we expect a new GHG replacementproposed rule to be proposed in March 2023.

In May 2023, the EPA regulatory timeline, we expect aproposed to revise the New Source Performance Standards for GHG emissions from new, modified, and reconstructed fossil-fueled power plants. The EPA is proposing two distinct 111(b) rules – one for natural gas-fired stationary combustion turbines and the other for coal-fired units. New stationary combustion turbine units would be divided into three subcategories based on their annual capacity factor – low load, intermediate load, and base load. Our RICE units are not affected by this rule to be proposed in March 2023.since each unit is below 25 MWs. We continue to move forward on the ESG Progress Plan, which is heavily focused on reducing GHG emissions.

The EPA released proposed regulations for the Mandatory Greenhouse Gas Reporting Rule, 40 Code of Federal Regulations Part 98, in June 2022. In May 2023, the EPA released a supplementary proposal, which includes updates of the global warming potentials to determine CO2 equivalency for threshold reporting and the addition of a new section regarding energy consumption. The proposed revisions could impact the reporting required for our electric generation facilities, local natural gas distribution companies, and underground natural gas storage facilities. In July 2023, the EPA also issued a pre-publication version of its proposal to amend reporting requirements for petroleum and natural gas systems, with an anticipated final rule to be issued in early 2024. We are currently evaluating the potential impact, if any, of the proposed rule.

Our ESG Progress Plan includes the retirement of older, fossil-fueled generation, to be replaced with zero-carbon-emitting renewables and clean natural gas-fueled generation. We have already retired more than 1,800 MW1,900 MWs of coal-firedfossil-fueled generation since the beginning of 2018. Through our ESG Progress Plan, we expect to retire approximately 1,600 MW1,500 MWs of additional fossil-fueled generation by the end of 2026, which includes the planned retirements in 2024-2025 of OCPP Units 5-8 and the planned retirement by June 2026 of jointly-owned Columbia Units 1-2. See Note 23, Regulatory Environment,7, Property, Plant, and Equipment, for more information on the timing of the retirements. In May 2021, we announced goals to achieve reductions in carbon emissions from our electric generation fleet by 60% by the end of 2025 and by 80% by the end of 2030, both from a 2005 baseline. We expect to achieve these goals by making operating refinements, retiring less efficient generating units, and executing our capital plan. Over the longer term, the target for our generation fleet is net-zero CO2 emissions by 2050.

We also continue to reduce methane emissions by improving our natural gas distribution system,systems, and have set a target across our natural gas distribution operations to achieve net-zero methane emissions by the end of 2030. We plan to achieve our net-zero goal through an effort that includes both continuous operational improvements and equipment upgrades, as well as the use of RNG throughout our utility systems.

Clean Water Act Cooling Water Intake Structure Rule

In August 2014, theThe EPA issued a final regulation under Section 316(b) of the Clean Water ActCWA that became effective in October 2014 and requires the location, design, construction, and capacity of cooling water intake structures at existing power plants to reflect the BTA for minimizing adverse environmental impacts. The federal rule became effective in October 2014 and applies to all of our existing generating facilities with cooling water intake structures, except for the ERGS units, which were permitted and received a final BTA determination under the rules governing new facilities.

In 2016,Pursuant to a WDNR rule, which became effective in June 2020, the WDNR initiated a state rulemaking process to incorporate therequirements of federal Section 316(b) requirementsof the CWA were incorporated into the Wisconsin Administrative Code. This new stateThe WDNR applies this rule NR 111, became effective in June 2020, and the WDNR will apply it when establishing BTA requirements for cooling water intake structures at existing facilities. These BTA requirements are incorporated into WPDES permits for WE and WPS facilities.

We have received a final BTA determination for Valley power plant. We have received interim BTA determinations for PWGS, OCPP Units 5-8, and Weston Units 2, 3 and 4. We believe that existing technology at the PWGS satisfies the BTA requirements; however, a final determination will not be made until the WPDES permit is renewed for this facility, which is expected to be by the third quarter of 2022. We also believe that existing technology installed at the OCPP facility meets the BTA requirements; however, depending on the timing of the permit reissuance, all 4four generating units at the OCPP may be retired prior to the WDNR making a final BTA decision, anticipated in 2025. In addition, we believe that existing technology installed at the Weston facility will result in a final BTA determination during the WPDES permit reissuance in 2023.

We are engaged in discussions with the WDNR regarding the current status of the BTA determination at PWGS. There is uncertainty about whether existing technology meets all of the WDNR's BTA requirements. We will not be in a position to determine what, if any, modifications may be needed at PWGS until the WDNR issues the WPDES permit renewal for PWGS, expected during the third quarter of 2023.

As a result of past capital investments completed to address Section 316(b) compliance at WE and WPS, we believe our fleet overall is well positioned to continue to meet this regulation and do not expect to incur significant additional compliance costs.regulation.

Steam Electric Effluent Limitation Guidelines

The EPA's final 2015 ELG rule, took effect ineffective January 2016 and was modified in 2020, to reviserevised the treatment technology requirements related to BATW and wet FGD wastewaters at existing facilities. This rulecoal-fueled facilities and created new requirements for several types of power plant wastewaters. The 2two new requirements that affect WE and WPS facilities relate to discharge limits for BATW and wet FGD wastewater. OurAlthough our power plant facilities already have advanced wastewater treatment technologies installed that meet many of the discharge limits established by this rule. There will, however, need to berule, certain facility modifications are necessary to meet water permit requirements for the ELG rule requirements. Through 2023, we expect that compliance costs associated with the ELG rule will require $105 million in capital investment. An $8 million BATW system at Weston Unit 3, which is expected to be completed by December 2023. Modificationsmodification to OC 7 and OC 8 werewas completed and placed in-service in mid-2021. Wastewater treatment system modifications also will be required for wet FGD dischargesmid-2021, and site wastewater from the ERGS units. Based on engineering cost estimates, we expect that compliance with the ELG rule will require $100 millionin capital investment. In December 2021, the PSCW Division of Energy Regulation and Analysis issued a Certificate of Authority approving the $89 million ERGS FGD wastewater treatment system modification. The BATW modifications, doincluding $8 million of modifications at Weston Unit 3 completed in June 2023, did not require PSCW

approval prior to construction. All of these ELG required projects are either in-service or are on track for completion by the WPDES permit deadlinedeadlines in December 2023.

In July 2021,March 2023, the EPA announcedissued the proposed "supplemental ELG rule." The rule would replace the existing 2020 ELG rule and, as proposed, would establish stricter limitations on: 1) BATW; 2) FGD wastewater; 3) CCR leachate; and 4) legacy wastewaters. The most significant proposed ELG rule change is a ZLD requirement for FGD wastewater. Under the proposed rule, this new ZLD requirement must be met by a date determined by the permitting authority (the WDNR for WE) that it intends to initiate rulemaking to reviseis as soon as possible beginning 60 days following publication of the ELG Rule as modified in 2020. The EPA has stated that the ELG Rule will continue to be implemented and enforced while the agency pursues this rulemaking process. The EPA plans to propose a revisedfinal rule, in the fall of 2022.but no later than December 31, 2029.

The proposed rule would also create a subcategory for "early adopters" that have already installed a compliant biological treatment system by the date of the proposed rule. Early adopters would not be required to install further FGD wastewater treatment, provided the facility owner also agrees to permanently cease combustion of coal by December 31, 2032. Although we are currently completing an $89 million biological treatment system at ERGS, which we expect to be complete later this year, the expected timing of the project's completion would not comply with the deadline imposed by the EPA to qualify for early adopter status. In addition, we do not believe that, upon its completion, the biological treatment system would be compliant with the additional ZLD FGD wastewater treatment requirements as proposed. In May 2023, we submitted written comments to the EPA.

If the supplemental ELG rule is finalized as proposed, we anticipate that our coal-fueled facilities will meet the BATW rule provisions. BATW projects were completed at Weston Unit 3 in June 2023 and at the OCPP Units 7 and 8 in June 2021. ERGS Units 1 and 2 and OCPP Units 5 and 6 were both built with ELG-compliant dry BATW systems.

The EPA also proposed requirements for legacy wastewaters and landfill leachate. We are reviewing those proposed requirements to determine potential costs and actions required for our facilities.

Waters of the United States

In December 2021,January 2023, the EPA and the United States Army Corps of Engineers together released a proposedfinal rule to repealeffective in March 2023, that based the April 2020 Navigable Waters Protection Rule that defined WOTUS. The purposedefinition of this proposed rule will be to restore regulations defining WOTUS that were in place prior to 2015 and to update certain provisions to be consistent with relevant Supreme Court decisions.on its pre-2015 definition. The pre-2015 approach involves applying factors established through case law and agency precedents to determine whether a wetland or surface drainage feature is subject to federal jurisdiction.

In January 2022,May 2023, the Supreme Court granted certiorariissued a decision significantly narrowing federal jurisdiction over wetlands. In Sackett v. Environmental Protection Agency, the court ruled that the federal government's jurisdiction over WOTUS extends to "traditional navigable waters" and wetlands or other waters that have a "continuous surface connection" with a traditional navigable water.

Following the Supreme Court decision, the agencies announced they would interpret the definition of WOTUS consistent with the Sackett decision. The agencies are also developing a new rule to amend the definition of WOTUS that was published in the Federal Register in January 2023, to be consistent with the Sackett decision. The agencies have indicated that they intend to issue a case to evaluatenew final rule by September 2023.

We anticipate the proper test for determining whether wetlands are WOTUS.Sackett decision will cause a decrease in the number of projects that require Army Corps federal wetland permits. The Sackett decision may also affect the administration of some state programs. At this point, our projects requiring federal permits are moving ahead, but we are monitoring these recent developments to better understand potential future impacts. This case, once decided, should provide clarity regarding the definition of WOTUS. We will continue to monitor this litigation and any subsequent agency action.

Manufactured Gas Plant Remediation

We have identified sites at which our utilities or a predecessor company owned or operated a manufactured gas plant or stored manufactured gas. We have also identified other sites that may have been impacted by historical manufactured gas plant activities. Our natural gas utilities are responsible for the environmental remediation of these sites, some of which are in the EPA Superfund Alternative Approach Program. We are also working with various state jurisdictions in our investigation and remediation planning. These sites are at various stages of investigation, monitoring, remediation, and closure.

In addition, we are coordinating the investigation and cleanup of some of these sites subject to the jurisdiction of the EPA under what is called a "multisite" program. This program involves prioritizing the work to be done at the sites, preparation and approval of documents common to all of the sites, and use of a consistent approach in selecting remedies. At this time, we cannot estimate future remediation costs associated with these sites beyond those described below.

The future costs for detailed site investigation, future remediation, and monitoring are dependent upon several variables including, among other things, the extent of remediation, changes in technology, and changes in regulation. Historically, our regulators have allowed us to recover incurred costs, net of insurance recoveries and recoveries from potentially responsible parties, associated with the remediation of manufactured gas plant sites. Accordingly, we have established regulatory assets for costs associated with these sites.

We have established the following regulatory assets and reserves for manufactured gas plant sites:

Coal Combustion Residuals Rule

The EPA issued a pre-publication proposed rule for CCR in May 2023, that would apply to all landfills, historic fill sites, and projects where CCR was placed. As proposed, the rule would regulate previously exempt closed landfills and would include sites we own as well as several third party owned properties.

We are actively engaged with the Utility Solid Waste Activities Group and the EEI in evaluating and commenting on this rule. The proposed rule could have a material adverse impact on our coal ash landfills and require additional remediation that has not been required under the current state programs.

Enforcement and Litigation Matters

We and our subsidiaries are involved in legal and administrative proceedings before various courts and agencies with respect to matters arising in the ordinary course of business. Although we are unable to predict the outcome of these matters, management believes that appropriate reserves have been established and that final settlement of these actions will not have a material impact on our financial condition or results of operations.

NOTE 23—25—REGULATORY ENVIRONMENT

Recovery of Natural Gas Costs

Due to the cold temperatures, wind, snow, and ice throughout the central part of the country during February 2021, the cost of gas purchased for our natural gas utility customers was temporarily driven significantly higher than our normal winter weather expectations. All of our utilities have regulatory mechanisms in place for recovering all prudently incurred gas costs.

In March 2021, WE and WG received approval from the PSCW to recover approximately $54 million and $24 million, respectively, of natural gas costs in excess of the benchmark set in their GCRMs over a period of three months, beginning in April 2021. In March 2021, WPS also filed its revised natural gas rate sheets with the PSCW reflecting approximately $28 million of natural gas costs in excess of the benchmark set in its GCRM. WPS also recovered these excess costs over a period of three months, beginning in April 2021.

PGL and NSG incurred approximately $131 million and $10 million, respectively, of natural gas costs in February 2021 in excess of the amounts included in their rates. These costs were recovered over a period of 12 months, which started on April 1, 2021. PGL's and NSG's natural gas costs are being reviewed for prudency by the ICC as part of their annual natural gas cost reconciliation. The ICC could order the refund of any costs determined to be imprudent as part of the reconciliation. A decision regarding this review is expected by the end of 2022.

In February 2021, MERC incurred approximately $75 million of natural gas costs in excess of the benchmark set in its GCRM. In August 2021, the MPUC issued a written order approving a joint proposal filed by MERC and 4 other Minnesota utilities to recover their respective excess natural gas costs. MERC will recover $10 million of these costs through its annual natural gas true-up process over a period of 12 months, and the remaining $65 million over 27 months, both of which started in September 2021. Recovery of these costs and the issue of prudence has been referred to a contested-case proceeding. As a result of the proceeding, the MPUC could disallow recovery or order the refund of any costs determined to be imprudent. A decision regarding this review is expected during the third quarter of 2022.

Natural gas costs incurred at MGU and UMERC in excess of the amount included in their respective rates were not significant.

Wisconsin Electric Power Company, Wisconsin Public Service Corporation, and Wisconsin Gas LLC

2023 and 2024 RatesLimited Rate Case Re-Opener

In Aprilaccordance with their rate orders approved by the PSCW in December 2022, WE, WPS, and WG filed requests for limited electric and natural gas rate case re-openers, as applicable, with the PSCW to increase their retail electric, natural gas, and steam rates, as applicable, effective January 1,on May 15, 2023. The requested increases inlimited electric ratesrate case re-openers filed by WE and WPS include updated revenue requirements for the generation projects that were driven by capital investments in new wind, solar, and battery storage; capital investments in natural gas generation; reliability investments, including grid hardening projects to bury power lines and strengthen WE's distribution system against severe weather; and changes in wholesale business with other utilities. Many of these investments have already been approved by the PSCW. The requested increases in natural gas rates primarily related to capital investments previously approved by the PSCW including LNG storage for our natural gas distribution system.

In July 2022, WE, WPS, and WG updated their rate requests to reflect recent developments that impacted, as applicable, the respective utility's original proposal for rate increases in 2023. These recent developments included:

Delays in the in-service dates of Darien and the battery portion of Paris due to supply chain disruptions.
WE's decision to extend the operating life of the OCPP due to tight energy supply conditions in MISO and the delay in the renewable energy projects discussed above. The expected retirement of the OCPP units 5 and 6 was delayed one year, until May 2024, and the retirement of units 7 and 8 was delayed approximately 18 months, until late 2025.
Wisconsin Power & Light Company's decision to delay the retirements of the jointly-owned Columbia units. The retirements of the Columbia units, which were originally planned for the end of 2023 and 2024, were delayed until 2026. WPS holds a 27.5% ownership interest in these units.
Increases in the cost of Badger Hollow II.
The effect of anticipated increases in interest rates on borrowing costs.

WE and WPS are seeking a limited rate case re-opener for 2024 to address additional revenue requirements associated with generation projects that are expected to be placed into service in 2023 and 2024. In addition,WE's limited electric re-opener also includes the projected savings from the retirement of the OCPP units 5 and 6, which are expected to be retired in May 2024.

The Peoples Gas Light and Coke Company and North Shore Gas Company

2023 Rate Case

In January 2023, PGL and NSG filed requests with the ICC to increase their natural gas rates. They are requesting incremental rate increases of $194.7 million (13.0%) and $18.7 million (7.8%), respectively. The requested rate increases are primarily driven by capital investments made to strengthen the safety and reliability of each utility’s natural gas distribution system. PGL is also seeking to recover costs incurred to upgrade its natural gas storage field and operations facilities and to continue improving customer service.

Both companies are requesting an ROE of 9.90% and a common equity component average of 54.0%. PGL is not seeking an extension of the QIP rider. Instead, PGL will return to the traditional rate making process to recover the costs of necessary infrastructure improvements. See the Qualifying Infrastructure Plant Rider section below for more information on the QIP rider.

An ICC decision is anticipated in the fourth quarter of 2023, with any rate adjustments expected to be effective January 1, 2023.2024.

The Peoples Gas Light and Coke Company

Qualifying Infrastructure Plant Rider

In July 2013, Illinois Public Act 98-0057, The Natural Gas Consumer, Safety & Reliability Act, became law. This law provides natural gas utilities with a cost recovery mechanism that allows collection, through a surcharge on customer bills, of prudently incurred costs to upgrade Illinois natural gas infrastructure. In January 2014, the ICC approved a QIP rider for PGL, which is in effect through 2023. PGL will not seek an extension of the rider beyond 2023.

PGL's QIP rider is subject to an annual reconciliation whereby costs are reviewed for accuracy and prudency. In March 2022,2023, PGL filed its 20212022 reconciliation with the ICC, which, along with the 2020, 2019, 2018, 2017, andreconciliations from 2016 reconciliations,through 2021, are still pending.

As of June 30, 2022,2023, there can be no assurance that all costs incurred under PGL's QIP rider during the open reconciliation years, which include 2016 through 2022, will be deemed recoverable by the ICC.

2023 Rate Case

In November 2022, MERC initiated a rate proceeding with the MPUC to increase its retail natural gas base rates by $40.3 million (9.9%). MERC's request reflected a 10.3% ROE and a common equity component average of 53.0%. The proposed retail natural gas rate increase was primarily driven by increased capital investments as well as inflationary pressure on operating costs. In December 2022, the MPUC approved MERC's request for interim rates totaling $37.0 million, subject to refund. The interim rates went into effect on January 1, 2023.

On May 11, 2023, MERC filed with the MPUC a settlement agreement it reached with certain intervenors. The settlement agreement reflects a natural gas base rate increase of $28.8 million (7.1%), along with a 9.65% ROE and a common equity component average of 53.0%. Under the terms of the settlement agreement, MERC will continue the use of its decoupling mechanism for residential customers, and it will be expanded to include certain small commercial and industrial customers. The settlement agreement is pending MPUC approval. MERC’s customers will be entitled to a refund to the extent the interim rate increase exceeds the final approved rate increase. We expect a decision from the MPUC in the fourth quarter of 2023.

Michigan Gas Utilities Corporation

2023 Rate Case

In March 2023, MGU filed a request with the MPSC to increase its retail natural gas base rates by $19.1 million (9.1%). The request reflected a 10.4% ROE and a common equity component average of 51.4%. MGU also requested changes to its MRP rider, including updates for projects that are expected to be placed into service during 2023 and 2024, updates to remaining project costs to address inflation, and an extension of the rider for an additional two years (new expiration of 2029).

The proposed natural gas rate increase was primarily driven by capital investments made to strengthen the safety and reliability of MGU's natural gas distribution system and to provide service to additional customers. Inflationary pressure on operating costs also contributed to the proposed rate increase.

In July 2023, MGU reached a comprehensive settlement that resolves all issues in its rate case. The settlement agreement is being finalized and is expected be filed with the MPSC for approval shortly.

An MPSC decision is anticipated in the second half of 2023, with new rates expected to be effective January 1, 2024.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

CORPORATE DEVELOPMENTS

The following discussion should be read in conjunction with the accompanying unaudited financial statements and related notes and our 20212022 Annual Report on Form 10-K.

Introduction

We are a diversified holding company with natural gas and electric utility operations (serving customers in Wisconsin, Illinois, Michigan, and Minnesota), an approximately 60% equity ownership interest in American Transmission Company LLC (ATC) (a for-profit electric transmission company regulated by the Federal Energy Regulatory Commission and certain state regulatory commissions), and non-utility energy infrastructure operations through W.E. Power, LLC (which owns generation assets in Wisconsin)Wisconsin that it leases to Wisconsin Electric Power Company (WE)), Bluewater Natural Gas Holding, LLC (which owns underground natural gas storage facilities in Michigan), and WEC Infrastructure LLC (WECI), which holds ownership interests in several windrenewable generating facilities.

Corporate Strategy

Our goal is to continue to build and sustain long-term value for our shareholders and customers by focusing on the fundamentals of our business: environmental stewardship; reliability; operating efficiency; financial discipline; exceptional customer care; and safety. Our capital investment plan for efficiency, sustainability and growth, referred to as our ESG Progress Plan, provides a roadmap for us to achieve this goal. It is an aggressive plan to cut emissions, maintain superior reliability, deliver significant savings for customers, and grow our investment in the future of energy.

Throughout our strategic planning process, we take into account important developments, risks and opportunities, including new technologies, customer preferences and affordability, energy resiliency efforts, and sustainability. We published the results of a priority sustainability issue assessment in 2020, identifying the issues that are most important to our company and its stakeholders over the short and long terms. Our risk and priority assessments have formed our direction as a company.

Creating a Sustainable Future

Our ESG Progress Plan includes the retirement of older, fossil-fueled generation, to be replaced with zero-carbon-emitting renewables and clean natural gas-fired generation. When taken together, the retirements and new investments should better balance our supply with our demand, while maintaining reliable, affordable energy for our customers. The retirements will contribute to meeting our goals to reduce carbon dioxide (CO2) emissions from our electric generation.

In May 2021, weWe have announced goals to achieve reductions in carbon emissions from our electric generation fleet by 60% by the end of 2025 and by 80% by the end of 2030, both from a 2005 baseline. We expect to achieve these goals by making operating refinements, retiring less efficient generating units, and executing our capital plan. Over the longer term, the target for our generation fleet is net-zero CO2 emissions by 2050.

As part of our path toward these goals, we are exploring co-firing with natural gas at our ERGSElm Road Generating Station (ERGS) coal-fired units. By the end of 2030, we expect to use coal as a backup fuel only, and we believe we will be in a position to eliminate coal as an energy source by the end of 2035.

We already have retired more than 1,800 megawatts (MW)1,900 MWs of coal-firedfossil-fueled generation since the beginning of 2018, which included the 2019 retirement of the Presque Isle power plant as well as the 2018 retirements of the Pleasant Prairie power plant, the Pulliam power plant, and the jointly-owned Edgewater Unit 4 generating units. Through our ESG Progress Plan, we expect to retire approximately 1,600 MW1,500 MWs of additional fossil-fueled generation by the end of 2026, which includes the planned retirement in 2024-2025 of Oak Creek Power Plant Units 5-8 and the planned retirement inby June 2026 of jointly-owned Columbia Units 1-2. See Note 23, Regulatory Environment, for information on the delay of these planned retirements.

In addition to retiring these older, fossil-fueled plants, we expect to invest approximately $3.5$5.4 billion from 2022-20262023-2027 in regulated renewable energy in Wisconsin. Our plan is to replace a portion of the retired capacity by building and owning zero-carbon-emitting renewable generation facilities that are anticipated to include the following new investments:

1,400 MW1,900 MWs of utility-scale solar;
800 MW700 MWs of battery storage; and

100 MW600 MWs of wind.

We also plan on investing in a combination of clean, natural gas-fired generation, including:

100 MW of reciprocating internal combustion engine (RICE) natural gas-fueled generation;
including the planned purchase of up to 200 MW100 MWs of additional capacity in the West Riverside Energy Center — a combined-cyclecombined cycle natural gas plant recently completed and operated by Alliant Energy in Wisconsin; and
the planned purchase of the Whitewater Cogeneration Facility, a natural gas-fired combined-cycle electric generating facility with a capacity of 236.5 MW.Wisconsin.

The new investments discussed above are in addition to the renewable projects currently underway. For more details, see Liquidity and Capital Resources – Cash Requirements – Significant Capital Projects.

In addition, we are investing in 300 MW of utility-scale solar within our Wisconsin segment. Wisconsin Public Service Corporation (WPS) partnered with an unaffiliated utility to construct two solar projects now in service in Wisconsin: Two Creeks Solar Park (Two Creeks) and Badger Hollow Solar Park I (Badger Hollow I). WPS owns 100 MW of Two Creeks and 100 MW of Badger Hollow I for a total of 200 MW. Wisconsin Electric Power Company (WE) has partnered with an unaffiliated utility to construct Badger Hollow Solar Park II, which is expected to enter commercial operation in the first half of 2023. Once constructed, WE will own 100 MW of this project.

In December 2018, WE received approval from the PSCWPublic Service Commission of Wisconsin (PSCW) for two renewable energy pilot programs. The Solar Now pilot is expected to add a total of 35 MWMWs of solar generation to WE's portfolio, allowing non-profit and governmental entities, as well as commercial and industrial customers, to site utility owned solar arrays on their property. Under this program, WE has energized 2325 Solar Now projects and currently has another threefour under construction, together totaling more than 29 MW.30 MWs. The second program, the Dedicated Renewable Energy Resource (DRER) pilot, would allow large commercial and industrial customers to access renewable resources that WE would operate, addingand could add up to 150 MW35 MWs of renewables to WE's portfolio, and helpingportfolio. The DRER pilot would help these larger customers meet their sustainability and renewable energy goals. In July 2023, WE and Wisconsin Public Service Corporation (WPS) received approval from the PSCW for the Renewable Pathway Pilot, the third renewable energy program. This program allows commercial and industrial customers to subscribe to a portion of a utility-scale, Wisconsin-based renewable energy generating facility. The Renewable Pathway Pilot will utilize generation from Paris Solar-Battery Park, Darien Solar-Battery Park, and Red Barn Wind Park and will have a participation cap of 125 MW at WE and 40 MW at WPS.

In August 2021, the PSCW approved pilot programs for WE and WPS to install and maintain electric vehicle (EV) charging equipment for customers at their homes or businesses. The programs provide direct benefits to customers by removing cost barriers associated with installing EV equipment. In October 2021, subject to the receipt of any necessary regulatory approvals, we pledged to expand the EV charging network within the service territories of our electric utilities. In doing so, we joined a coalition of utility companies in a unified effort to make EV charging convenient and widely available throughout the Midwest. The coalition we joined is planning to help build and grow EV charging corridors, enabling the general public to safely and efficiently charge their vehicles.

We also continue to reduce methane emissions by improving our natural gas distribution system. We set a target across our natural gas distribution operations to achieve net-zero methane emissions by the end of 2030. We plan to achieve our net-zero goal through an effort that includes both continuous operational improvements and equipment upgrades, as well as the use of renewable natural gas (RNG) throughout our natural gas utility systems. In 2022, we received approval from the PSCW for our RNG pilots and wepilots. We have since signed our first threesix contracts for RNG for our natural gas distribution business, which will be transporting the output of local dairy farms onto our gas distribution system.systems. The RNG supplied will directly replace higher-emission methane from natural gas that would have entered our pipes. These threesix contracts represent approximately 80 percentbring us to over one Bcf of RNG planned to enter our 2030 goal for methane reduction. Wesystems, and we expect to have RNG flowing in 2023, supporting our goal to our distribution network by the end of 2022.reduce methane emissions.

As part of our effort to look for new opportunities in sustainable energy, during 2022 we arecompleted testing the effects of blending hydrogen, a clean generating fuel, with natural gas for one of our RICE generating units in the Upper Peninsula of Michigan. We are partneringpartnered with the Electric Power Research Institute (EPRI) in this research that could help create another viable option for decarbonizing the economy. The project is being carried out in 2022, and the results will beof this testing were shared across the industry.earlier this year by EPRI.

06/30/2022 Form 10-Q44WEC Energy Group, Inc.
We are planning for the start of a pilot program in the fourth-quarter of 2023 with EPRI and CMBlu Energy, a Germany-based designer and manufacturer, to test a new form of long-duration energy storage on the U.S. electric grid. The program will test battery system performance, including the ability to store and discharge energy for up to twice as long as the typical lithium-ion batteries in use today.

Reliability

We have made significant reliability-related investments in recent years, and in accordance with our ESG Progress Plan, expect to continue strengthening and modernizing our generation fleet, as well as our electric and natural gas distribution networks to further improve reliability.

06/30/2023 Form 10-Q44WEC Energy Group, Inc.


Table of Contents
Below are a few examples of reliability projects that are proposed, currently underway, or recently completed.

WE and Wisconsin Gas LLC (WG) have received approval to each construct their own liquefied natural gas (LNG) facility to meet anticipated peak demand. Commercial operation of the WE and WG LNG facilities is targeted for the end of 2023 and 2024, respectively.

The Peoples Gas Light and Coke Company continues to work on its Safety Modernization Program, which primarily involves replacing old iron pipes and facilities in Chicago’s natural gas delivery system with modern polyethylene pipes to reinforce the long-term safety and reliability of the system.

Our utilities continue to upgrade their electric and natural gas distribution systems to enhance reliability.reliability and storm hardening.

We expect to spend approximately $3.4$3.6 billion from 20222023 to 20262027 on reliability related projects with continued investment anticipated over the next decade. For more details, see Liquidity and Capital Resources – Cash Requirements – Significant Capital Projects.

Operating Efficiency

We continually look for ways to optimize the operating efficiency of our company and will continue to do so under the ESG Progress Plan. For example, we are making progress on our Advanced Metering Infrastructure program, replacing aging meter-reading equipment on both our network and customer property. An integrated system of smart meters, communication networks, and data management programs enables two-way communication between our utilities and our customers. This program reduces the manual effort for disconnects and reconnects and enhances outage management capabilities.

We continue to focus on integrating the resources of all our businesses and finding the best and most efficient processes.

Financial Discipline

A strong adherence to financial discipline is essential to meeting our earnings projections and maintaining a strong balance sheet, stable cash flows, a growing dividend, and quality credit ratings.

We follow an asset management strategy that focuses on investing in and acquiring assets consistent with our strategic plans, as well as disposing of assets, including property, plants, equipment, and entire business units, that are no longer strategic to operations, are not performing as intended, or have an unacceptable risk profile. See Note 3, Disposition,Dispositions, for information on a recent transaction.transactions.

Our investment focus remains in our regulated utility and non-utility energy infrastructure businesses, as well as our investment in ATC. In our non-utility energy infrastructure segment, we have acquired or agreed to acquire majority interests in eight wind parks and two solar parks, with total available capacity of more than 1,550 MW.2,000 MWs. These renewable energy assets represent more than $2.3$2.9 billion in committed investments and have long-term agreements to serve customers outside our traditional service areas. Production tax credits from these windrenewable investments reduce our cash tax expense. In addition, we anticipate that credits generated in 2023 and beyond will be eligible to be transferred to third parties in exchange for cash. See Note 2, Acquisitions, for information on recent and pending transactions.

We expect total capital expenditures for our regulated utility and non-utility energy infrastructure businesses to be approximately $16.4$18.1 billion from 20222023 to 2026.2027. In addition, we currently forecast that our share of ATC's projected capital expenditures over the next five years will be $1.3approximately $2.0 billion. Specific projects included in the $17.7$20.1 billion ESG Progress Plan are discussed in more detail below under Liquidity and Capital Resources – Cash Requirements – Significant Capital Projects.

Earnings increased $11.5$2.2 million during the second quarter of 2022,2023, compared with the same quarter in 2021.2022. The significant factors impacting the $11.5$2.2 million increase in earnings were:

A $12.8$37.2 million increase in net income attributed to common shareholders at the Wisconsin segment, driven by an increase in electric and natural gas margins related to the impact of the Wisconsin rate orders approved by the PSCW, effective January 1, 2023, and a positive quarter-over-quarter impact from collections of fuel and purchased power costs. See Note 26, Regulatory Environment, in our 2022 Annual Report on Form 10-K for more information on the 2023 rate orders. These positive impacts were partially offset by a decrease in margins due to lower weather-driven electric and natural gas sales volumes, and higher operating expenses, including increases in expenses related to transmission and depreciation and amortization.

A $5.6 million increase in net income attributed to common shareholders at the non-utility energy infrastructure segment, driven by an increase in PTCs in 2023, primarily related to the acquisition of three additional renewable generation facilities in the second half of 2022 and the first quarter of 2023. Partially offsetting this increase was higher interest expense, primarily due to intercompany financing costs, which are offset by higher interest income at the corporate and other segment.

These increases in earnings were partially offset by:

A $26.3 million decrease in net income attributed to common shareholders at the Illinois segment, driven by higher operation and maintenance expense due to the quarter-over-quarter impact of a gain recorded in the second quarter of 2022 on the sale of certain real estate in Chicago, as well as higher natural gas margins due to PGL's continued capital investment inby PGL and the SMP project under its QIP rider.impact from a 2023 ICC order associated with an annual prudency review of the UEA Rider.

December 2021, an increase in the PTC rate related to the PTC inflation adjustment issued by the IRS, and higher generation at our other wind parks.

A $1.9 million increase in net income attributed to common shareholders at the Wisconsin segment, driven by an increase in natural gas margins related to higher retail sales volumes, primarily due to the continued economic recovery in Wisconsin from the COVID-19 pandemic, as well as colder weather during the second quarter of 2022, compared with the same quarter in 2021. Also contributing to the increase in earnings was lower operation and maintenance expense, driven by the amortization of certain regulatory liabilities to offset a portion of our 2022 forecasted revenue deficiencies, and higher net credits from the non-service components of our net periodic pension and OPEB costs. The amortization of the regulatory liabilities was approved by the PSCW in order to forego filing for 2022 base rate increases. See Note 26, Regulatory Environment, in our 2021 Annual Report on Form 10-K for additional information on our 2022 Wisconsin base rates. These increases in earnings were partially offset by the negative impact from actual fuel and purchased power costs compared with costs collected in rates and higher depreciation and amortization.

These increases in earnings were partially offset by a $16.9$15.4 million increase in net loss attributed to common shareholders at the corporate and other segment, driven by higher interest expense. This negative impact was partially offset by net lossesgains from the investments held in the Integrys rabbi trust during the second quarter of 2022,2023, compared with net gainslosses during the same quarter in 2021.2022, and an increase in intercompany interest income, which is offset by higher interest expense at our operating segments. The gains and losses from the investments held in the rabbi trust partially offset the changes in benefitsbenefit costs related to deferred compensation, which are primarily included in other operation and maintenance expense in our operatingutility segments. See Note 13,15, Fair Value Measurements, for more information on our investments held in the Integrys rabbi trust. A decrease in earnings from our equity method investments in technology and energy-focused investment funds also contributed to the decrease in earnings.

Non-GAAP Financial Measures

The discussions below address the contribution of each of our segments to net income attributed to common shareholders. The discussions include financial information prepared in accordance with GAAP, as well as electric margins and natural gas margins, which are not measures of financial performance under GAAP. Electric margins (electric revenues less fuel and purchased power costs) and natural gas margins (natural gas revenues less cost of natural gas sold) are non-GAAP financial measures because they exclude other operation and maintenance expense, depreciation and amortization, and property and revenue taxes.

We believe that electric and natural gas margins provide a useful basis for evaluating utility operations since the majority of prudently incurred fuel and purchased power costs, as well as prudently incurred natural gas costs, are passed through to customers in current rates. As a result, management uses electric and natural gas margins internally when assessing the operating performance of our segments as these measures exclude the majority of revenue fluctuations caused by changes in these expenses. Similarly, the presentation of electric and natural gas margins herein is intended to provide supplemental information for investors regarding our operating performance.

Our electric margins and natural gas margins may not be comparable to similar measures presented by other companies. Furthermore, these measures are not intended to replace operating income as determined in accordance with GAAP as an indicator of operating performance. The following table shows operating income by segment for our utility operations during the second quarter of 20222023 and 2021:2022:

(1)Represents transmission expense that our electric utilities are authorized to collect in rates. The PSCW has approved escrow accounting for ATC and MISO network transmission expenses for WE and WPS. As a result, WE and WPS defer as a regulatory asset or liability, the difference between actual transmission costs and those included in rates until recovery or refund is authorized in a future rate proceeding. During the second quarter of 2023 and 2022, and 2021, $130.1$127.9 million and $124.8$130.1 million, respectively, of costs were billed to our electric utilities by transmission providers.

During the second quarter of 2022, WE and WPS amortized $20.3 million of the regulatory liabilities associated with their transmission escrows to offset certain 2022 revenue deficiencies, as approved by the PSCW in order to forego filing for 2022 base rate increases. This amortization drove the decrease inlower transmission expense during the second quarter of 2022, compared with the same quarter in 2021. See Note 26, Regulatory Environment, in our 2021 Annual Report on Form 10-K for additional information on 2022 Wisconsin base rates.2022.

Electric Revenues

Electric revenues increased $133.5 million during the second quarter of 2022, compared with the same quarter in 2021. To the extent that changes in fuel and purchased power costs are passed through to customers, the changes are offset by comparable changes in revenues. See the discussion of electric utility margins below for more information related to the recovery of fuel and purchased power costs and the remaining drivers of the changes in electric revenues.

Electric Utility Margins

Electric utility margins at the Wisconsin segment increased $6.7 million during the second quarter of 2022, compared with the same quarter in 2021. The significant factors impacting the higher electric utility margins were:

An $18.3 million increase in margins related to the impact of unprotected excess deferred taxes during the second quarter of 2021, which we agreed to return to customers in our PSCW-approved rate orders. This increase in margins is offset in income taxes.

A $2.0 million increase in securitization revenues received during the second quarter of 2022, compared with the same quarter in 2021, related to an environmental control charge collected from WE's retail electric distribution customers on behalf of WEPCo Environmental Trust. WE began assessing this charge in June 2021, subsequent to the issuance of the ETBs by WEPCo Environmental Trust in May 2021, in accordance with a November 2020 PSCW financing order. See Note 20, Variable Interest Entities, for more information. These revenues are offset in depreciation and amortization as well as interest expense.

A $4.2 million increase in other revenues, primarily related to third party use of our assets.

These increases in margins were partially offset by:

A $14.2 million quarter-over-quarter negative impact from actual fuel and purchased power costs compared with costs collected in rates. Under the Wisconsin fuel rules, the margins of our electric utilities are impacted by under- or over-collections of certain fuel and purchased power costs that are within a 2% price variance from the costs included in rates, and the remaining variance beyond the 2% price variance is generally deferred for future recovery or refund to customers.

Lower margins of $4.7 million driven by the expiration of certain wholesale contracts.

Natural Gas Revenues

Natural gas revenues increased $116.4 million during the second quarter of 2022, compared with the same quarter in 2021. Because prudently incurred natural gas costs are passed through to our customers in current rates, the changes are offset by comparable changes in revenues. The average per-unit cost of natural gas increased 55% during the second quarter of 2022, compared with the same quarter in 2021. The remaining drivers of changes in natural gas revenues are described in the discussion of natural gas utility margins below.

Natural Gas Utility Margins

Natural gas utility margins at the Wisconsin segment increased $13.6 million during the second quarter of 2022, compared with the same quarter in 2021. The significant factors impacting the higher natural gas utility margins were:

An $11.4 million increase in margins from higher sales volumes, driven by the continued economic recovery in Wisconsin from the COVID-19 pandemic, as well as colder weather during the second quarter of 2022, compared with the same quarter in 2021. As measured by heating degree days, the second quarter of 2022 was 13.8% and 6.3% colder than the same quarter in 2021 in the Milwaukee area and Green Bay area, respectively.

A $2.5 million increase in margins related to amortization of a certain portion of WG's regulatory liability consisting of credit balances associated with the escrow of natural gas storage service costs from Bluewater Gas Storage, LLC. In September 2021, the PSCW issued a written order for our Wisconsin utilities approving certain accounting treatments to offset certain 2022

revenue deficiencies in order to forego filing for 2022 base rate increases. See Note 26, Regulatory Environment, in our 2021 Annual Report on Form 10-K for more information.

Other Operating Expenses (includes other operation and maintenance, depreciation and amortization, and property and revenue taxes)

Other operating expenses at the Wisconsin segment increased $2.7 million during the second quarter of 2022, compared with the same quarter in 2021. The significant factors impacting the increase in operating expenses were:

A $12.8 million increase in electric and natural gas distribution expenses, primarily driven by higher storm restoration expense during the second quarter of 2022, and higher costs to maintain system reliability.

A $7.9 million increase in depreciation and amortization, driven by assets being placed into service as we continue to execute on our capital plan, an increase related to the We Power leases, and an increase related to securitization amortization, which is offset in revenues. These increases were partially offset by $2.5 million of deferred depreciation related to capital investments made by WG since it's last rate case, as approved by the PSCW in an order that allowed our Wisconsin utilities to offset certain 2022 revenue deficiencies in order to forego filing for 2022 base rate increases. See Note 26, Regulatory Environment, in our 2021 Annual Report on Form 10-K for more information.

A $3.6 million increase in regulatory amortizations and other pass through expenses, as discussed in the notes under the other operation and maintenance table above.

A $3.0 million increase in benefits, primarily driven by higher stock-based compensation and pension costs, partially offset by lower deferred compensation costs.

These increases in other operating expenses were partially offset by:

A $20.2 million decrease in transmission expense driven by the amortization of a certain portion of WE's and WPS's regulatory liabilities associated with transmission escrow balances, as discussed in the notes under the other operation and maintenance table above.

A $5.4 million decrease in expense driven by the amortization of a certain portion of WPS's regulatory liability associated with its 2020 earnings sharing mechanism, as discussed in the notes under the other operation and maintenance table above.

Other Income, Net

Other income, net at the Wisconsin segment increased $6.3 million during the second quarter of 2022, compared with the same quarter in 2021, driven by higher net credits from the non-service components of our net periodic pension and OPEB costs. See Note 16, Employee Benefits, for more information on our benefit costs.

Interest Expense

Interest expense at the Wisconsin segment decreased $4.2 million during the second quarter of 2022, compared with the same quarter in 2021, primarily due to the deferral of interest expense related to capital investments made by WG since its last rate case, as approved by the PSCW in an order that allowed our Wisconsin utilities to offset certain 2022 revenue deficiencies in order to forego filing for a 2022 base rate increase. See Note 26, Regulatory Environment, in our 2021 Annual Report on Form 10-K for more information. Also contributing to the decrease was lower interest expense on finance lease liabilities, primarily related to the WE Power leases, as finance lease liabilities decrease each year as payments are made.

Income Tax Expense

Income tax expense at the Wisconsin segment increased $26.2 million during the second quarter of 2022, compared with the same quarter in 2021. The increase in income tax expense was due to an approximate $18 million negative impact related to the lower quarter-over-quarter amortization of the unprotected excess deferred tax benefits from the Tax Legislation in connection with the Wisconsin rate orders approved by the PSCW, effective January 1, 2020. The impact due to the benefit from the amortization of the unprotected excess deferred tax benefits in 2021 from the Tax Legislation did not impact earnings as there was an offsetting impact

in operating income. Also contributing to this increase in income tax expense was an increase in pre-tax income in 2022. See Note 12, Income Taxes, for more information.

Illinois Segment Contribution to Net Income Attributed to Common Shareholders

The Illinois segment's contribution to net income attributed to common shareholders was $56.4 million during the second quarter of 2022, representing a $12.8 million, or 29.4%, increase over the same quarter in 2021. The increase was driven by a gain on the sale of certain real estate in Chicago, as well as higher natural gas margins due to PGL's continued capital investment in the SMP project under its QIP rider. See Note 3, Disposition, for more information on the sale. These positive impacts were partially offset by increases in various operating expenses, including expenses related to the settlement of legal claims, charitable projects, and benefit costs.

Since the majority of PGL and NSG customers use natural gas for heating, net income attributed to common shareholders at the Illinois segment is sensitive to weather and is generally higher during the winter months.

Natural Gas Revenues

Natural gas revenues increased $166.9 million during the second quarter of 2022, compared with the same quarter in 2021. Because prudently incurred natural gas costs are passed through to our customers in current rates, the changes are offset by comparable changes in revenues. The average per-unit cost of natural gas increased 234% during the second quarter of 2022, compared with the same quarter in 2021. The remaining drivers of changes in natural gas revenues are described in the discussion of margins below.

Natural Gas Utility Margins

Natural gas utility margins at the Illinois segment, net of the $3.7 million impact of the riders referenced in the table above, increased $6.6 million during the second quarter of 2022, compared with the same quarter in 2021. The increase in margins was primarily driven by:

A $6.2 million increase in revenues at PGL due to continued capital investment in the SMP project. PGL recovers the costs related to the SMP through a surcharge on customer bills pursuant to an ICC approved QIP rider, which is in effect through 2023. See Note 23, Regulatory Environment, for more information.

A $1.8 million increase related to the impact of the NSG rate order approved by the ICC, effective September 15, 2021, which includes the Variable Income Tax Adjustment Rider in base rates. See Note 26, Regulatory Environment, in our 2021 Annual Report on Form 10-K for additional information on the 2021 rate order.

These increases in natural gas utility margins were partially offset by a $2.2 million decrease in fixed charges during the second quarter of 2022, compared with the same quarter in 2021.

Other Operating Expenses (includes other operation and maintenance, depreciation and amortization, and property and revenue taxes)

Other operating expenses at the Illinois segment decreased $10.4 million, net of the $3.7 million impact of the riders referenced in the table above, during the second quarter of 2022, compared with the same quarter in 2021. The significant factor impacting the decrease in operating expenses was a $54.5 million pre-tax gain on the sale of certain real estate in Chicago. See Note 3, Disposition, for more information.

This decrease in operating expenses related to the pre-tax gain was partially offset by:

An $11.4 million increase in expenses associated with the settlement of legal claims.

A $10.0 million increase in expenses related to charitable projects supporting our customers and the communities within our service territories.

An $8.4 million increase in benefit costs, primarily due to higher pension and stock-based compensation costs.

A $4.9 million increase in natural gas distribution and maintenance costs.

A $3.4 million increase in depreciation expense, primarily driven by PGL's continued capital investment in the SMP project.

A $2.4 million increase in costs associated with maintenance at the Manlove Gas Storage Field.

A $1.6 million increase in customer service expense, primarily driven by higher call volumes.

A $1.6 million increase in property and revenue taxes, primarily driven by an increase in the invested capital tax related to continued capital investment. This increase was offset in natural gas utility margins.

Other Income, Net

Other income, net at the Illinois segment increased $2.4 million during the second quarter of 2022, compared with the same quarter in 2021, driven by higher net credits from the non-service components of our net periodic pension and OPEB costs. See Note 16, Employee Benefits, for more information on our benefit costs.

Interest Expense

Interest expense at the Illinois segment increased $1.4 million during the second quarter of 2022, compared with the same quarter in 2021, primarily due to $225.0 million of long-term debt issuances in November 2021.

Income Tax Expense

Income tax expense at the Illinois segment increased $5.2 million during the second quarter of 2022, compared with the same quarter in 2021, driven by an increase in pre-tax income.

Other States Segment Contribution to Net Income Attributed to Common Shareholders

The other states segment's contribution to net income attributed to common shareholders during the second quarter of 2022 was $2.7 million, representing a $0.2 million, or 8.0%, increase over the same quarter in 2021. The increase was driven by higher natural gas margins due to a rate increase at MGU, effective January 1, 2022, and higher retail sales volumes during the second quarter of 2022, compared with the same quarter in 2021. These positive impacts were partially offset by increases in operating expenses, as well as interest expense, as discussed below.

Since the majority of MERC and MGU customers use natural gas for heating, net income attributed to common shareholders at the other states segment is sensitive to weather and is generally higher during the winter months.

See the discussion of natural gas utility margins below for the remaining drivers of changes in natural gas revenues.

Natural Gas Utility Margins

Natural gas utility margins increased $4.4 million during the second quarter of 2022, compared to the same quarter in 2021. The increase in margins was primarily driven by:

A $2.3 million increase related to the new rates at MGU that went into effect in 2022.

A $1.6 million increase related to higher retail sales volumes due to both colder weather in our Minnesota service territories and continued economic recovery during the second quarter of 2022, as compared to the same quarter in 2021.

Other Operating Expenses (includes other operation and maintenance, depreciation and amortization, and property and revenue taxes)

Other operating expenses at the other states segment increased $2.7 million during the second quarter of 2022, compared to the same quarter in 2021. The significant factors impacting the increase in operating expenses were:

A $1.5 million increase in natural gas operations and customer service expense, driven by various operation and maintenance projects approved in MGU's rate case and higher labor and external contracting costs.

A $0.8 million increase in depreciation and amortization related to continued capital investment.

Interest Expense

Interest expense at the other states segment increased $1.7 million during the second quarter of 2022, compared with the same quarter in 2021, primarily due to the deferral of $1.2 million of interest expense in the second quarter of 2021, as approved by the MPSC to mitigate the impacts from delaying the filing of its 2021 rate case. See Note 26, Regulatory Environment, in our 2021 Annual Report on Form 10-K for additional information. This deferred interest expense is now being amortized over a four-year period as a result of MGU's approved rate increase.

Operating Income

Operating income at the non-utility energy infrastructure segment increased $3.6 million during the second quarter of 2022, compared with the same quarter in 2021. The increase was primarily due to a $3.7 million positive impact from a sharing arrangement with one of our Blooming Grove customers resulting from strong energy prices.

Income Tax Expense (Benefit)

At the non-utility energy infrastructure segment, $7.3 million of income tax benefit was recorded during the second quarter of 2022, compared with $0.7 million of income tax expense recorded during the same quarter in 2021. The change was primarily due to a $9.3 million increase in PTCs in 2022, driven by the Jayhawk wind park achieving commercial operation in December 2021, an increase in the PTC rate related to the PTC inflation adjustment issued by the IRS, and higher generation at our other wind parks. This favorable change in the income tax benefit was partially offset by higher pre-tax earnings during the second quarter of 2022, compared with same quarter in 2021.

Operating Loss

The operating loss at the corporate and other segment increased $2.2 million during the second quarter of 2022, compared with the same quarter in 2021. The higher operating loss was driven by $2.6 million of gains on land sales at Wispark during the second quarter of 2021, which did not reoccur in the second quarter of 2022.

Other Income (Expense), Net

The corporate and other segment had other expense, net of $8.9 million during the second quarter of 2022, compared with other income, net of $19.9 million during the same quarter in 2021. The $28.8 million decrease in other income was driven by a $9.7 million net loss from the investments held in the Integrys rabbi trust during the second quarter of 2022, compared with a $6.0 million net gain during the same quarter in 2021. The gains and losses from the investments held in the rabbi trust partially offset the changes in benefits costs related to deferred compensation, which are included in other operation and maintenance expense in our operating segments. See Note 13, Fair Value Measurements, for more information on our investments held in the Integrys rabbi trust. A $13.7 million decrease in earnings from our equity method investments in technology and energy-focused investment funds also contributed to the decrease in other income.

Income Tax Expense (Benefit)

The corporate and other segment recorded a $10.0 million income tax benefit during the second quarter of 2022, compared with $4.1 million of income tax expense during the same quarter in 2021. The positive change in income taxes was driven by a higher pre-tax loss. Also contributing to the favorable change in the income tax benefit were a $2.0 million increase in excess tax benefits recognized related to stock option exercises and a $1.9 million increase in the interim tax benefit recorded to adjust consolidated income tax expense to the projected, annualized consolidated effective income tax rate, during the six months ended June 30, 2022, compared with the same period in 2021.

Earnings increased $67.3 million during the six months ended June 30, 2022, compared with the same period in 2021. The significant factors impacting the $67.3 million increase in earnings were:

A $33.7 million increase in net income attributed to common shareholders at the Wisconsin segment, driven by an increase in natural gas margins related to higher retail sales volumes, primarily due to the continued economic recovery in Wisconsin from the COVID-19 pandemic, as well as colder weather during the six months ended June 30, 2022, compared with the same period in 2021. Also contributing to the increase in earnings was lower operation and maintenance expense, driven by the amortization of certain regulatory liabilities to offset a portion of our 2022 forecasted revenue deficiencies, and higher net credits from the non-service components of our net periodic pension and OPEB costs. The amortization of the regulatory liabilities was approved by the PSCW in order to forego filing for 2022 base rate increases. These increases in earnings were partially offset by higher depreciation and amortization and the negative impact from actual fuel and purchased power costs compared with costs collected in rates.

A $31.6 million increase in net income attributed to common shareholders at the non-utility energy infrastructure segment, driven by an increase in PTCs during 2022, primarily due to the Jayhawk wind park that achieved commercial operation in December 2021, an increase in the PTC rate related to the PTC inflation adjustment issued by the IRS, and higher generation at our other wind parks. Also contributing to the increase in net income was the recognition of revenue related to market settlements Upstream received from SPP in February 2021. Due to a complaint filed with the FERC, the revenue related to these settlements could not be recognized until the FERC issued an order denying the complaint in the first quarter of 2022.

A $14.1 million increase in net income attributed to common shareholders at the Illinois segment, driven by a gain on the sale of certain real estate in Chicago, as well as higher natural gas margins due to PGL's continued capital investment in the SMP project under its QIP rider and NSG's rate increase, effective September 15, 2021. These positive impacts were partially offset by increases in various operating expenses, including expenses related to the settlement of legal claims, charitable projects, and benefit costs.

These increases in earnings were partially offset by a $20.9 million decrease in earnings from the corporate and other segment, driven by net losses from the investments held in the Integrys rabbi trust during the first half of 2022, compared with net gains during the same period in 2021. A decrease in earnings from our equity method investments in technology and energy-focused investment funds also contributed to the decrease in earnings.

Expected 2022 Annual Effective Tax Rate

We expect our 2022 annual effective tax rate to be between 18.5% and 19.5%. Our effective tax rate calculations are revised every quarter based on the best available year-end tax assumptions, adjusted in the following year after returns are filed. Tax accrual estimates are trued-up to the actual amounts claimed on the tax returns and further adjusted after examinations by taxing authorities, as needed.

Non-GAAP Financial Measures

The discussions below address the contribution of each of our segments to net income attributed to common shareholders. The discussions include financial information prepared in accordance with GAAP, as well as electric margins and natural gas margins, which are not measures of financial performance under GAAP. Electric margins (electric revenues less fuel and purchased power costs) and natural gas margins (natural gas revenues less cost of natural gas sold) are non-GAAP financial measures because they exclude other operation and maintenance expense, depreciation and amortization, and property and revenue taxes.

We believe that electric and natural gas margins provide a useful basis for evaluating utility operations since the majority of prudently incurred fuel and purchased power costs, as well as prudently incurred natural gas costs, are passed through to customers in current rates. As a result, management uses electric and natural gas margins internally when assessing the operating performance of our segments as these measures exclude the majority of revenue fluctuations caused by changes in these expenses. Similarly, the presentation of electric and natural gas margins herein is intended to provide supplemental information for investors regarding our operating performance.

Our electric margins and natural gas margins may not be comparable to similar measures presented by other companies. Furthermore, these measures are not intended to replace operating income as determined in accordance with GAAP as an indicator of operating performance. The following table shows operating income by segment for our utility operations during the six months ended June 30, 2022 and 2021:

Wisconsin Segment Contribution to Net Income Attributed to Common Shareholders

The Wisconsin segment's contribution to net income attributed to common shareholders was $436.5 million during the six months ended June 30, 2022, representing a $33.7 million, or 8.4%, increase over the same period in 2021. The higher earnings were driven by an increase in natural gas margins related to higher retail sales volumes, primarily due to the continued economic recovery in Wisconsin from the COVID-19 pandemic, as well as colder weather during the six months ended June 30, 2022, compared with the same period in 2021. Also contributing to the increase in earnings was lower operation and maintenance expense, driven by the amortization of certain regulatory liabilities to offset a portion of our 2022 forecasted revenue deficiencies, and higher net credits from the non-service components of our net periodic pension and OPEB costs.

The PSCW has approved escrow accounting for ATC and MISO network transmission expenses for WE and WPS. As a result, WE and WPS defer as a regulatory asset or liability, the difference between actual transmission costs and those included in rates until recovery or refund is authorized in a future rate proceeding. During the six months ended June 30, 2022 and 2021, $256.6 million and $255.4 million, respectively, of costs were billed to our electric utilities by transmission providers.

During the six months ended June 30, 2022, WE and WPS amortized $40.5 million of the regulatory liabilities associated with their transmission escrows to offset certain 2022 revenue deficiencies, as approved by the PSCW in order to forego filing for 2022 base rate increases. This amortization drove the decrease in transmission expense during the six months ended June 30, 2022, compared with the same period in 2021.

Electric Revenues

Electric revenues increased $224.7decreased $43.5 million during the six months ended June 30, 2022,second quarter of 2023, compared with the same periodquarter in 2021.2022. To the extent that changes in fuel and purchased power costs are passed through to customers, the changes are offset by comparable changes in revenues. See the discussion of electric utility margins below for more information related to the recovery of fuel and purchased power costs and the remaining drivers of the changes in electric revenues.

Electric Utility Margins

Electric utility margins at the Wisconsin segment increased $40.4$70.7 million during the six months ended June 30, 2022,second quarter of 2023, compared with the same periodquarter in 2021.2022. The significant factors impacting the higher electric utility margins were:

A $54.1$76.2 million increase in margins related to the impact of unprotected excess deferred taxes during the six months ended June 30, 2021, which we agreed to return to customersWisconsin rate orders approved by the PSCW, effective January 1, 2023. See Note 26, Regulatory Environment, in our PSCW-approved2022 Annual Report on Form 10-K for more information on the 2023 rate orders. This increase in margins is offset in income taxes.

A $5.3$22.0 million increasequarter-over-quarter positive impact from collections of fuel and purchased power costs. Under the Wisconsin fuel rules, the margins of our electric utilities are impacted by under- or over-collections of certain fuel and purchased power costs that are within a 2% price variance from the costs included in securitization revenues received duringrates, and the six months ended June 30, 2022, compared withremaining variance beyond the same period in 2021, related2% price variance is generally deferred for future recovery or refund to an environmental control charge collected from WE's retail electric distribution customers on behalf of WEPCo Environmental Trust. WE began assessing this charge in June 2021, subsequent to the issuance of the ETBs by WEPCo Environmental Trust in May 2021, in accordance with a November 2020 PSCW financing order. These revenues are offset in depreciation and amortization as well as interest expense.customers.

As measured by heating degree days, the six months ended June 30, 2022 were 8.0% and 9.6% colder than the same period in 2021 in the Milwaukee area and Green Bay area, respectively.Whitewater facility, effective January 1, 2023.

These increases in margins were partially offset by:

A $22.7 million decrease in margins related to lower sales volumes, driven by the impact of cooler spring weather during the second quarter of 2023, compared with the same quarter in 2022. As measured by cooling degree days, the second quarter of 2023 was 39.0% and 30.1% cooler than the same quarter in 2022 in the Milwaukee area and Green Bay area, respectively.

An $18.4$8.3 million decrease in other revenues, primarily related to third-party use of our assets and a FERC order in January 2023 that eliminated reactive power compensation MISO was required to pay to generators, including our electric utilities.

Natural Gas Revenues

Natural gas revenues decreased $89.4 million during the second quarter of 2023, compared with the same quarter in 2022. Because prudently incurred natural gas costs are passed through to our customers in current rates, the changes are offset by comparable changes in revenues. The average per-unit cost of natural gas decreased approximately 47% during the second quarter of 2023, compared with the same quarter in 2022. The remaining drivers of changes in natural gas revenues are described in the discussion of natural gas utility margins below.

Natural Gas Utility Margins

Natural gas utility margins at the Wisconsin segment increased $12.6 million during the second quarter of 2023, compared with the same quarter in 2022. The most significant factor impacting the higher natural gas utility margins was a $17.3 million increase in margins related to the impact of the Wisconsin rate orders approved by the PSCW, effective January 1, 2023. This increase in margins was partially offset by a $4.9 million decrease in margins from lower sales volumes, driven by warmer weather during the second quarter of 2023, compared with the same quarter in 2022. As measured by heating degree days, the second quarter of 2023 was 9.8% and 3.9% warmer than the same quarter in 2022 in the Milwaukee area and Green Bay area, respectively. See Note 26, Regulatory Environment, in our 2022 Annual Report on Form 10-K for more information on the 2023 rate orders.

Other Operating Expenses (includes other operation and maintenance, depreciation and amortization, and property and revenue taxes)

Other operating expenses at the Wisconsin segment increased $40.1 million during the second quarter of 2023, compared with the same quarter in 2022. The significant factors impacting the increase in other operating expenses were:

A $24.2 million increase in transmission expense as approved in the PSCW's 2023 rate orders, effective January 1, 2023. See the notes under the other operation and maintenance table above for more information. This amount is net of a deferral of $6.4 million approved by the PSCW in June 2023, retroactive to December 1, 2022, in response to a FERC order eliminating reactive power compensation to our utilities, as discussed in electric margins above.

A $22.6 million increase in depreciation and amortization, driven by assets being placed into service as we continue to execute on our capital plan.

A $14.6 million increase in regulatory amortizations and other pass through expenses, as discussed in the notes under the other operation and maintenance table above.

An $8.2 million increase in other operation and maintenance expense related to the We Power leases, as discussed in the notes under the other operation and maintenance table above.

A $6.0 million increase in other operating and maintenance related to our power plants, driven by increased maintenance, including planned outages at the Weston power plant, and operating costs associated with Whitewater, which was purchased in January 2023.

A $4.6 million increase in expense related to the earnings sharing mechanism in place at our Wisconsin utilities, as discussed in the notes under the other operation and maintenance table above.

These increases in other operating expenses were partially offset by:

A $22.2 million pre-tax gain on the sale of land at our Pleasant Prairie power plant site during the second quarter of 2023. See Note 3, Dispositions, for more information.

A $13.8 million decrease in benefit costs, primarily driven by lower stock-based compensation and incentive costs.

A $4.7 million decrease in electric and natural gas distribution expenses, primarily driven by lower costs to maintain the distribution system and for storm restoration during the second quarter of 2023, compared with the same quarter in 2022.

Other Income, Net

Other income, net at the Wisconsin segment increased $12.8 million during the second quarter of 2023, compared with the same quarter in 2022, driven by higher AFUDC–Equity due to continued capital investment.

Interest Expense

Interest expense at the Wisconsin segment increased $14.5 million during the second quarter of 2023, compared with the same quarter in 2022, primarily due to the impact of WE and WPS issuing long-term debt during the third and fourth quarters of 2022, respectively, and higher short-term debt interest rates. Also contributing to the increase was the deferral in the second quarter of 2022 of $2.0 million of interest expense related to capital investments made by WG since its 2020 rate case, as approved by the PSCW in an order that allowed our Wisconsin utilities to offset certain 2022 revenue deficiencies in order to forego filing for 2022 base rate increases. This deferred interest expense is now being amortized over a two-year period. See Note 26, Regulatory Environment, in our 2022 Annual Report on Form 10-K for more information. These increases were partially offset by higher AFUDC–Debt due to continued capital investment.

Income Tax Expense

Income tax expense at the Wisconsin segment increased $4.3 million during the second quarter of 2023, compared with the same quarter in 2022. The increase in income tax expense was due to higher pre-tax income, partially offset by a $3.6 million increase in PTCs.

Illinois Segment Contribution to Net Income Attributed to Common Shareholders

The Illinois segment's contribution to net income attributed to common shareholders was $30.1 million during the second quarter of 2023, representing a $26.3 million, or 46.6%, decrease over the same quarter in 2022. The decrease was driven by higher operation and maintenance expense due to the quarter-over-quarter impact of a gain recorded in the second quarter of 2022 on the sale of certain real estate by PGL and the impact from a 2023 ICC order associated with an annual prudency review of the UEA Rider. See Factors Affecting Results, Liquidity, and Capital Resources – Regulatory, Legislative, and Legal Matters – Regulatory Recovery for more information on the ICC order. These negative impacts were partially offset by decreases in certain other operating expenses, including expenses related to the settlement of legal claims, charitable projects, and benefit costs.

Since the majority of PGL and NSG customers use natural gas for heating, net income attributed to common shareholders is sensitive to weather and is generally higher during the winter months.

Natural Gas Revenues

Natural gas revenues decreased $168.9 million during the second quarter of 2023, compared with the same quarter in 2022. Because prudently incurred natural gas costs are passed through to our customers in current rates, the changes are offset by comparable changes in revenues. The average per-unit cost of natural gas decreased 75% during the second quarter of 2023, compared with the same quarter in 2022. The remaining drivers of changes in natural gas revenues are described in the discussion of margins below.

Natural Gas Utility Margins

Natural gas utility margins at the Illinois segment, net of the $8.9 million impact of the riders referenced in the table above, increased $5.0 million during the second quarter of 2023, compared with the same quarter in 2022. The increase in margins was primarily driven by a $5.7 million increase in revenues at PGL due to continued capital investment in the SMP project. PGL recovers the costs related to the SMP through a surcharge on customer bills pursuant to an ICC approved QIP rider, which is in effect through the end of 2023. See Note 25, Regulatory Environment, for more information.

Other Operating Expenses (includes other operation and maintenance, depreciation and amortization, and property and revenue taxes)

Other operating expenses at the Illinois segment increased $36.0 million, net of the $8.9 million impact of the riders referenced in the table above, during the second quarter of 2023, compared with the same quarter in 2022. The significant factors impacting the increase in other operating expenses were:

A $54.5 million pre-tax gain on the sale of certain real estate in Chicago during the second quarter of 2022. See Note 3, Dispositions, for more information.

An $11.1 million increase in expenses driven by an ICC order received in May 2023 related to an annual prudency review of PGL's and NSG's UEA Rider, which requires a refund to ratepayers starting in September 2023. See Factors Affecting Results, Liquidity, and Capital Resources – Regulatory, Legislative, and Legal Matters – Regulatory Recovery for more information.

An $8.4 million increase in expenses due to a ratemaking adjustment related to certain capitalized costs during the second quarter of 2023.

These increases in other operating expenses were partially offset by:

A $10.2 million decrease in expenses associated with the settlement of legal claims during the second quarter of 2022.

Other income, net at the Illinois segment decreased $2.2 million during the second quarter of 2023, compared with the same quarter in 2022, driven by lower net credits from the non-service components of our net periodic pension and OPEB costs. See Note 18, Employee Benefits, for more information on our benefit costs.

Interest Expense

Interest expense at the Illinois segment increased $3.4 million during the second quarter of 2023, compared with the same quarter in 2022, primarily due to increased short-term debt interest rates and PGL's issuance of long-term debt in December 2022.

Income Tax Expense

Income tax expense at the Illinois segment decreased $10.3 million during the second quarter of 2023, compared with the same quarter in 2022, driven by a decrease in pre-tax income.

Other States Segment Contribution to Net Income Attributed to Common Shareholders

The other states segment's contribution to net income attributed to common shareholders was $3.7 million during the second quarter of 2023, representing a $1.0 million, or 37.0%, increase over the same quarter in 2022. The increase in earnings was driven by higher natural gas margins due to an interim rate increase at MERC, effective January 1, 2023, and a decrease in operating expenses driven by lower benefit costs. These positive impacts were partially offset by an increase in interest expense.

Since the majority of MERC and MGU customers use natural gas for heating, net income attributed to common shareholders at the other states segment is sensitive to weather and is generally higher during the winter months.

Natural Gas Revenues

Natural gas revenues decreased $18.0 million during the second quarter of 2023, compared with the same quarter in 2022. Because prudently incurred natural gas costs are passed through to our customers in current rates, the changes are offset by comparable changes in revenues. The average per-unit cost of natural gas decreased approximately 22% during the second quarter of 2023, compared with the same quarter in 2022. See the discussion of natural gas utility margins below for the remaining drivers of changes in natural gas revenues.

Natural Gas Utility Margins

Natural gas utility margins increased $2.1 million during the second quarter of 2023, compared with the same quarter in 2022. The primary factor impacting the increase in natural gas utility margins was a $2.4 million increase related to an interim rate increase at MERC that was effective January 1, 2023. See Note 25, Regulatory Environment, for more information about the pending rate case.

Other Operating Expenses (includes other operation and maintenance, depreciation and amortization, and property and revenue taxes)

Other operating expenses at the other states segment decreased $0.7 million during the second quarter of 2023, compared with the same quarter in 2022. The primary factor impacting the decrease in operating expenses was a $1.7 million decrease in benefit costs, primarily due to lower stock-based compensation and incentive costs. This decrease in other operating expenses was partially offset by a $1.1 million increase in natural gas operations and customer service expense, driven by various operation and maintenance projects at MERC.

Interest Expense

Interest expense at the other states segment increased $0.9 million during the second quarter of 2023, compared with the same quarter in 2022, primarily due to higher short-term debt interest rates.

Income Tax Expense

Income tax expense at the other states segment increased $0.4 million during the second quarter of 2023, compared with the same quarter in 2022, driven by an increase in pre-tax income.

Interest Expense

Interest expense at the non-utility energy infrastructure segment increased $7.7 million during the second quarter of 2023, compared with the same quarter in 2022, primarily due to a $5.4 million increase in interest expense due to WECI’s issuance of a $430.0 million long-term intercompany note payable to WEC Energy Group in April 2023. Also driving the increase was WECI Wind Holding II's issuance of long-term debt in December 2022.

Income Tax Benefit

The income tax benefit at the non-utility energy infrastructure segment increased $12.4 million during the second quarter of 2023, compared with the same quarter in 2022. The increase was primarily due to a $10.7 million increase in PTCs in the second quarter of 2023, driven by the acquisition of three additional renewable generation facilities in the second half of 2022 and the first quarter of 2023.

Other Income (Expense), Net

The corporate and other segment had other income, net of $15.9 million during the second quarter of 2023, compared with other expense, net of $8.9 million during the same quarter in 2022. The significant factors impacting the change in other income (expense), net were:

A $4.4 million net gain from the investments held in the Integrys rabbi trust during the second quarter of 2023, compared with a $9.7 million net loss during the same quarter in 2022. The gains and losses from the investments held in the rabbi trust partially offset the changes in benefit costs related to deferred compensation, which are primarily included in other operation and maintenance expense in our utility segments. See Note 15, Fair Value Measurements, for more information on our investments held in the Integrys rabbi trust.

A $6.2 million increase in intercompany interest income, driven by WECI's issuance of a $430.0 million long-term intercompany note to WEC Energy Group in April 2023 and higher interest rates on short-term borrowings to subsidiaries in our operating segments.

A $3.3 million positive quarter-over-quarter impact due to a net loss from our equity method investments in technology and energy-focused investment funds during the second quarter of 2022.

Interest Expense

Interest expense at the corporate and other segment increased $37.4 million during the second quarter of 2023, compared with the same quarter in 2022, due to WEC Energy Group's issuance of long-term debt in September 2022, January 2023, and April 2023 and higher short-term debt interest rates.

Income Tax Benefit

The income tax benefit at the corporate and other segment decreased $2.7 million during the second quarter of 2023, compared with the same quarter in 2022. This decrease was driven by a $3.5 million quarter-over-quarter increase in the interim tax expense recorded to adjust consolidated income tax expense to the projected, annualized consolidated effective income tax rate. Also contributing to the decrease in the income tax benefit was a $2.2 million decrease in excess tax benefits recognized related to stock option exercises. These decreases in income tax benefit were partially offset by a higher pre-tax loss.

Earnings decreased $56.2 million during the six months ended June 30, 2023, compared with the same period in 2022. The significant factors impacting the $56.2 million decrease in earnings were:

A $42.8 million increase in net loss attributed to common shareholders at the corporate and other segment, driven by higher interest expense. This negative impact was partially offset by net gains from the investments held in the Integrys rabbi trust during the first half of 2023, compared with net losses during the same period in 2022.

A $26.6 million decrease in net income attributed to common shareholders at the Illinois segment, driven by higher operation and maintenance expense due to the period-over-period impact of a gain recorded in the second quarter of 2022 on the sale of certain real estate by PGL and the impact from a 2023 ICC order associated with an annual prudency review of the UEA Rider. These negative impacts were partially offset by decreases in certain other operating expenses and higher natural gas margins, primarily due to PGL's continued capital investment in the SMP project under its QIP rider.

These decreases in earnings were partially offset by a $6.3 million increase in net income attributed to common shareholders at the Wisconsin segment, driven by an increase in electric and natural gas margins due to the impact of the Wisconsin rate orders approved by the PSCW, effective January 1, 2023. This positive impact was partially offset by a decrease in electric and natural gas margins due to lower sales volumes, and higher operating expenses, including increases in expenses related to transmission, depreciation and amortization, and regulatory amortizations.

Expected 2023 Annual Effective Tax Rate

We expect our 2023 annual effective tax rate to be between 13.0% and 14.0%. Our effective tax rate calculations are revised every quarter based on the best available year-end tax assumptions, adjusted in the following year after returns are filed. Tax accrual estimates are trued-up to the actual amounts claimed on the tax returns and further adjusted after examinations by taxing authorities, as needed.

Non-GAAP Financial Measures

The discussions below address the contribution of each of our segments to net income attributed to common shareholders. The discussions include financial information prepared in accordance with GAAP, as well as electric margins and natural gas margins, which are not measures of financial performance under GAAP. Electric margins (electric revenues less fuel and purchased power costs) and natural gas margins (natural gas revenues less cost of natural gas sold) are non-GAAP financial measures because they exclude other operation and maintenance expense, depreciation and amortization, and property and revenue taxes.

We believe that electric and natural gas margins provide a useful basis for evaluating utility operations since the majority of prudently incurred fuel and purchased power costs, as well as prudently incurred natural gas costs, are passed through to customers in current rates. As a result, management uses electric and natural gas margins internally when assessing the operating performance

of our segments as these measures exclude the majority of revenue fluctuations caused by changes in these expenses. Similarly, the presentation of electric and natural gas margins herein is intended to provide supplemental information for investors regarding our operating performance.

Our electric margins and natural gas margins may not be comparable to similar measures presented by other companies. Furthermore, these measures are not intended to replace operating income as determined in accordance with GAAP as an indicator of operating performance. The following table shows operating income by segment for our utility operations during the six months ended June 30, 2023 and 2022:

Wisconsin Segment Contribution to Net Income Attributed to Common Shareholders

The Wisconsin segment's contribution to net income attributed to common shareholders was $442.8 million during the six months ended June 30, 2023, representing a $6.3 million, or 1.4%, increase over the same period in 2022. The higher earnings were driven by an increase in electric and natural gas margins due to the impact of the Wisconsin rate orders approved by the PSCW, effective January 1, 2023. This positive impact was partially offset by a decrease in electric and natural gas margins due to lower sales volumes, and higher operating expenses, including increases in expenses related to transmission, depreciation and amortization, and regulatory amortizations.

The PSCW has approved escrow accounting for ATC and MISO network transmission expenses for WE and WPS. As a result, WE and WPS defer as a regulatory asset or liability, the difference between actual transmission costs and those included in rates until recovery or refund is authorized in a future rate proceeding. During the six months ended June 30, 2023 and 2022, $255.2 million and $256.6 million, respectively, of costs were billed to our electric utilities by transmission providers.

During the six months ended June 30, 2022, WE and WPS amortized $40.5 million of the regulatory liabilities associated with their transmission escrows to offset certain 2022 revenue deficiencies, as approved by the PSCW in order to forego filing for 2022 base rate increases. This amortization drove the lower transmission expense during the six months ended June 30, 2022.

(2)Regulatory amortizations and other pass through expenses are substantially offset in margins and therefore do not have a significant impact on net income. Effective January 1, 2023, the PSCW approved escrow accounting for pension and OPEB costs as well as certain costs associated with our jointly-owned Columbia plant. As a result, our Wisconsin utilities defer as a regulatory asset or liability, the difference between these actual costs and those included in rates until recovery or refund is authorized in a future rate proceeding.

Electric Revenues

Electric revenues decreased $27.6 million during the six months ended June 30, 2023, compared with the same period in 2022. To the extent that changes in fuel and purchased power costs are passed through to customers, the changes are offset by comparable changes in revenues. See the discussion of electric utility margins below for more information related to the recovery of fuel and purchased power costs and the remaining drivers of the changes in electric revenues.

Electric Utility Margins

Electric utility margins at the Wisconsin segment increased $81.8 million during the six months ended June 30, 2023, compared with the same period in 2022. The significant factors impacting the higher electric utility margins were:

A $156.1 million increase in margins related to the impact of the Wisconsin rate orders approved by the PSCW, effective January 1, 2023.

An $11.5 million decrease in expense during the six months ended June 30, 2023, related to the expiration of a capacity contract driven by the acquisition of the Whitewater facility, effective January 1, 2023.

These increases in margins were partially offset by:

A $50.6 million decrease in margins related to lower sales volumes, driven by the impact of unfavorable weather during the six months ended June 30, 2023, compared with the same period in 2022. As measured by cooling degree days, the six months ended June 30, 2023 were 39.0% and 30.1% cooler than the same period in 2022 in the Milwaukee area and Green Bay area,

These negative impacts were partially offset by decreases in Chicago, as well ascertain other operating expenses and higher natural gas margins, primarily due to PGL's continued capital investment in the SMP project under its QIP rider and NSG's rate increase, effective September 15, 2021. These positive impacts were partially offset by increases in various operating expenses, including expenses related to the settlement of legal claims, charitable projects, and benefit costs.rider.

Interest expense at the non-utility energy infrastructure segment decreased $1.3increased $10.4 million during six months ended June 30, 2022, compared with the same period in 2021, primarily due to a lower principal balance as a result of the semi-annual principal payments on long-term debt.

Income Tax Expense (Benefit)

At the non-utility energy infrastructure segment, $12.2 million of income tax benefit was recorded during the six months ended June 30, 2022,2023, compared with $0.8 million of income tax expense recorded during the same period in 2021. 2022, primarily due to a $5.4 million increase in interest expense due to WECI’s issuance of a $430.0 million long-term intercompany note payable to WEC Energy Group in April 2023. Also driving the increase was WECI Wind Holding II's issuance of long-term debt in December 2022.

Income Tax Benefit

The changeincome tax benefit at the non-utility energy infrastructure segment increased $25.3 million during the six months ended June 30, 2023, compared with the same period in 2022. The increase was primarily due to an $18.5a $19.3 million increase in PTCs in 2022,2023, driven by the Jayhawk wind park that achieved commercial operation in December 2021, an increaseacquisition of three additional renewable generation facilities in the PTC rate relatedsecond half of 2022 and the first quarter of 2023. Also contributing to the PTC inflation adjustment issued by the IRS, and higher generation at our other wind parks. This favorable change in the income tax benefit was partially offset by highervariance were lower pre-tax earnings during the six months ended June 30, 2023, compared with the same period in 2022.

Our utilities continue to upgrade their electric and natural gas distribution systems to enhance reliability. These upgrades include addressing our aging infrastructure and system hardening and the AMI program. AMI is an integrated system of smart meters, communication networks, and data management systems that enable two-way communication between utilities and customers.

We are committed to investing in solar, wind, battery storage, and clean natural gas-fired generation. Below are examples of projects that are proposed or currently underway.underway:

We have received approval to invest in 100 MWMWs of utility-scale solar within our Wisconsin segment. WE has partnered with an unaffiliated utility to construct a solar project, Badger Hollow II, that will be located in Iowa County, Wisconsin. Once constructed, WE will own 100 MWMWs of this project. WE's share of the cost of this project is estimated to be approximately $151 million.$172 million. Commercial operation of Badger Hollow II is targeted for the first half of 2023.late 2023 or early 2024.

generation and 149 MWMWs of battery storage of this project. If approved, WE's and WPS's combined share of the cost of this project is estimated to be approximately $585 million, with construction of the solar portion expected to be completed in 2025.

In July 2023, WE and WPS received PSCW approval to constructcompleted construction of 128 MWs of natural gas-fired generation at WPS's existing Weston power plant site in northern Wisconsin. The new facility will consistconsists of seven RICE units. We estimateOur construction work in progress balance for the costWeston RICE units was $171.5 million as of this project to be approximately $170 million, with construction expected to be completed in 2023.

In November 2021, WE and WPS signed an asset purchase agreement to acquire Whitewater, a commercially operational 236.5 MW dual-fueled (natural gas and low sulfur fuel oil) combined-cycle electrical generation facility in Whitewater, Wisconsin. In December 2021, WE and WPS filed an application with the PSCW for approval to acquire Whitewater. If approved, the cost of this facility will be $72.7 million, with the transaction expected to close in earlyJune 30, 2023.

In January 2022,2023, WE and WPS along withcompleted the acquisition of Whitewater, a commercially operational 236.5 MW dual fueled (natural gas and low sulfur fuel oil) combined cycle electrical generation facility in Whitewater, Wisconsin. The cost of this facility was $76.0 million.

In June 2023, WE, closed on 100 MWs of capacity related to West Riverside for $95.3 million. West Riverside is a combined cycle natural gas plant completed and operated by an unaffiliated utility filedin Rock County, Wisconsin. In addition, WPS could exercise a second option to acquire an application with the PSCWadditional 100 MWs of capacity. WPS could also file for approval to acquire a portion of West Riverside's nameplate capacity. WPS is also requesting approval to assign the second option to purchase part of West Riverside to WE. If approved, WPS or WE would acquire 100 MW of capacity, in the first of two potential option exercises. West Riverside is a combined-cycle natural gas plant recently completed by an unaffiliated utility in Rock County, Wisconsin. If approved, our share of the cost of this ownership interest is expected to be approximately $91$100 million, with the transaction expected to close in the second quarter of 2023. In addition, WPS could exercise a second option to acquire an additional 100 MW of capacity.2024.

In March 2022, the DOC opened an investigation into whether new tariffs should be imposed on solar panels and cells imported from multiple southeast Asian countries.

solar projects as a result of the DOC investigation and CBP actions related to solar panels, respectively. The expected in-service dates and costs identified above already reflect some of these impacts.

WE and WG have received PSCW approval to each construct its own LNG facility. Each facility would provide approximately one billion cubic feetBcf of natural gas supply to meet anticipated peak demand without requiring the construction of additional interstate pipeline capacity. These facilities are expected to reduce the likelihood of constraints on WE's and WG's natural gas systems during the highest demand days of winter. The total cost of both projects is estimated to be approximately $370 million, with approximately half being invested by each utility. Commercial operation of the WE and WG LNG facilities is targeted for the end of 2023 and 2024, respectively.

PGL is continuing work on the SMP, a project under which PGL is replacing approximately 2,000 miles of Chicago's aging natural gas pipeline infrastructure. PGL currently recovers these costs through a surcharge on customer bills pursuant to an ICC approved QIP rider, which is in effect through 2023. After 2023, PGL will return to the traditional ratemaking process to recover the costs of necessary infrastructure improvements. PGL's projected average annual investment through 20242025 is between $280 million and $300 million.

The non-utility energy infrastructure line item in the table above includes WECI's plannedrecent investments in ThunderheadSapphire Sky and Sapphire Sky.Samson I, and its planned investment in Maple Flats. See Note 2, Acquisitions, for more information on these wind projects.

We expect to provide total capital contributions to ATC (not included in the above table) of approximately $115$244 million from 20222023 through 2024.2025. We do not expect to make any contributions to ATC Holdco during that period.

Other Significant Cash Requirements

See Note 21,23, Commitments and Contingencies, for information regarding our minimum future commitments related to purchase obligations for the procurement of fuel, power, and gas supply, as well as the related storage and transportation. There were no material changes to our other significant commitments outside the ordinary course of business during the six months ended June 30, 2022.2023.

Off-Balance Sheet Arrangements

We are a party to various financial instruments with off-balance sheet risk as a part of our normal course of business, including financial guarantees and letters of credit that support construction projects, commodity contracts, and other payment obligations. We believe that these agreements do not have, and are not reasonably likely to have, a current or future material effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures, or capital resources. For additional information, see Note 9,10, Short-Term Debt and Lines of Credit, Note 15,17, Guarantees, and Note 20,22, Variable Interest Entities.

Sources of Cash

Liquidity

We anticipate meeting our short-term and long-term cash requirements to operate our businesses and implement our corporate strategy through internal generation of cash from operations and access to the capital markets, which allows us to obtain external short-term borrowings, including commercial paper and term loans, and intermediate or long-term debt securities, as well as other
06/30/2023 Form 10-Q74WEC Energy Group, Inc.


Table of Contents
types of securities. Cash generated from operations is primarily driven by sales of electricity and natural gas to our utility customers, reduced by costs of operations. Our access to the capital markets is critical to our overall strategic plan and allows us to supplement cash flows from operations with external borrowings to manage seasonal variations, working capital needs, commodity price fluctuations, unplanned expenses, and unanticipated events.

WEC Energy Group, WE, WPS, WG, and PGL maintain bank back-up credit facilities, which provide liquidity support for each company's obligations with respect to commercial paper and for general corporate purposes. We review our bank back-up credit facility needs on an ongoing basis and expect to be able to maintain adequate credit facilities to support our operations.

The amount, type, and timing of any financings in 2022,for the remainder of 2023, as well as in subsequent years, will be contingent on investment opportunities and our cash requirements and will depend upon prevailing market conditions, regulatory approvals for certain subsidiaries, and other factors. Our regulated utilities plan to maintain capital structures consistent with those approved by their respective regulators. For more information on our utilitiesutilities' approved capital structures, see Item 1. Business – E. Regulation in our 20212022 Annual Report on Form 10-K.

The issuance of securities by our utility companies is subject to the approval of the applicable state commissions or FERC. Additionally, with respect to the public offering of securities, WEC Energy Group, WE, and WPS file registration statements with the SEC under the Securities Act of 1933, as amended (1933 Act). The amounts of securities authorized by the appropriate regulatory authorities, as well as the securities registered under the 1933 Act, are closely monitored and appropriate filings are made to ensure flexibility in the capital markets.

At June 30, 2022,2023, our current liabilities exceeded our current assets by $1,175.3$1,639.3 million. We do not expect this to have an impact on our liquidity as we currently believe that our cash and cash equivalents, our available capacity of $1,470.9$2,010.8 million under existing revolving credit facilities, cash generated from ongoing operations, and access to the capital markets are adequate to meet our short-term and long-term cash requirements.

Capitalization Structure

The following table shows our capitalization structure as of June 30, 2022,2023, as well as an adjusted capitalization structure that we believe is consistent with how a majority of the rating agencies currently view our 2007 Junior Notes:

The adjusted presentation of our consolidated capitalization structure is included as a complement to our capitalization structure presented in accordance with GAAP. Management evaluates and manages our capitalization structure, including our total debt to total capitalization ratio, using the GAAP calculation as adjusted to reflect the treatment of the 2007 Junior Notes by the majority of rating agencies. Therefore, we believe the non-GAAP adjusted presentation reflecting this treatment is useful and relevant to investors in understanding how management and the rating agencies evaluate our capitalization structure.

Debt Covenants

Certain of our short-term and long-term debt agreements contain financial covenants that we must satisfy, including debt to capitalization ratios and debt service coverage ratios. At June 30, 2022,2023, we were in compliance with all such covenants related to outstanding short-term and long-term debt. We expect to be in compliance with all such debt covenants for the foreseeable future. See Note 13, Short-Term Debt and Lines of Credit, Note 14, Long-Term Debt, and Note 11, Common Equity, in our 20212022 Annual Report on Form 10-K, for more information regarding our debt covenants.

Credit Rating Risk

Cash collateral postings and prepayments made with external parties, including postings related to exchange-traded contracts, and cash collateral posted by external parties were immaterial as of June 30, 2022.2023. From time to time, we may enter into commodity contracts that could require collateral or a termination payment in the event of a credit rating change to below BBB- at S&P Global Ratings, a division of S&P Global Inc., and/or Baa3 at Moody’s Investors Service, Inc. If WE had a sub-investment grade credit rating at June 30, 2022,2023, it could have been required to post $100 million of additional collateral or other assurances pursuant to the terms of a PPA. We also have other commodity contracts that, in the event of a credit rating downgrade, could result in a reduction of our unsecured credit granted by counterparties.

In addition, access to capital markets at a reasonable cost is determined in large part by credit quality. Any credit ratings downgrade could impact our ability to access capital markets.

On May 2, 2023, S&P Global Inc. affirmed WEC Energy Group’s ratings and revised its outlook to negative from stable, citing weakening financial measures. The ratings outlooks on our utilities remain stable. We do not believe the change in ratings outlook at WEC Energy Group will have a material impact on our ability to access capital markets.

Subject to other factors affecting the credit markets as a whole, we believe our current ratings should provide a significant degree of flexibility in obtaining funds on competitive terms. However, these security ratings reflect the views of the rating agency only. An explanation of the significance of these ratings may be obtained from the rating agency. Such ratings are not a recommendation to buy, sell, or hold securities. Any rating can be revised upward or downward or withdrawn at any time by a rating agency.

FACTORS AFFECTING RESULTS, LIQUIDITY, AND CAPITAL RESOURCES

The following is a discussion of certain factors that may affect our results of operations, liquidity, and capital resources. This discussion should be read together with the information in Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations – Factors Affecting Results, Liquidity, and Capital Resources in our 20212022 Annual Report on Form 10-K, which provides a more complete discussion of factors affecting us, including market risks and other significant risks, competitive markets, environmental matters, critical accounting policies and estimates, and other matters.

COVID-19 Pandemic

We have taken steps to mitigate the impact of the global COVID-19 pandemic. However, the extent to which the COVID-19 pandemic could continue to impact our results of operations and liquidity is largely dependent upon the ability of our customers to resume or maintain normal operations. Adverse impacts to us and our subsidiaries from a prolonged COVID-19 pandemic environment could include a decrease in revenues, increased bad debt expense, increases in past due accounts receivable balances, and access to the capital markets at unfavorable terms or rates.

We will continue to monitor COVID-19 pandemic-related developments affecting our workforce, customers, and suppliers and will implement additional actions that we determine to be necessary in order to mitigate any additional impacts. We cannot predict the full extent of the impacts of COVID-19, which will depend on, among other things, its duration through new variants, the rate and the effectiveness of both vaccinations and treatments, future regulatory and governmental actions, and the ability to maintain normal business activity.

Regulatory, Legislative, and Legal Matters

Regulatory Recovery

Our utilities account for their regulated operations in accordance with accounting guidance under the Regulated Operations Topic of the FASB Accounting Standard Codification. Regulated entities are allowed to defer certain costs that would otherwise be charged to expense if the regulated entity believes the recovery of those costs is probable. We record regulatory assets pursuant to generic and/or specific orders issued by our regulators. Recovery of the deferred costs in future rates is subject to the review and approval by those regulators. We assume the risks and benefits of ultimate recovery of these items in future rates. If the recovery of the deferred costs, including those referenced below, is not approved by our regulators, the costs would be charged to income in the current period. Regulators can impose liabilities on a prospective basis for amounts previously collected from customers and for
06/30/2023 Form 10-Q76WEC Energy Group, Inc.


Table of Contents
amounts that are expected to be refunded to customers. We record these items as regulatory liabilities. As of June 30, 2022,See Note 6, Regulatory Assets and Liabilities, for more information on our regulatory assets were $3,278.9and liabilities.

The rates of PGL and NSG include a UEA rider for cost recovery or refund of uncollectible expense based on the difference between actual uncollectible write-offs and the amounts recovered in rates. The UEA rider is subject to an annual reconciliation whereby costs are reviewed for accuracy and prudency by the ICC. On May 18, 2023, the ICC issued a written order on PGL's and NSG's 2018 UEA rider reconciliation, which requires a $15.4 million and $0.7 million refund to ratepayers at PGL and NSG, respectively. These amounts are to be refunded over a period of nine months, beginning September 1, 2023. PGL and NSG filed an application with the ICC requesting a rehearing of the May 18, 2023 order, but it was denied by the ICC on June 29, 2023. On July 11, 2023, PGL and NSG petitioned the Illinois Appellate Court for review of the ICC orders issued on May 18, 2023 and June 29, 2023. As a result of the orders issued by the ICC, our regulatory liabilities were $4,084.0 million.balance sheet at June 30, 2023 includes a liability for the combined $16.1 million of ordered refunds.

In January 2014, the ICC approved PGL's use of the QIP rider as a recovery mechanism for costs incurred related to investments in QIP. This rider is also subject to an annual reconciliation whereby costs are reviewed for accuracy and prudency. In March 2022,2023, PGL filed its 20212022 reconciliation with the ICC, which, along with the 2020, 2019, 2018, 2017, andreconciliations from 2016 reconciliations,through 2021, are still pending. As of June 30, 2022,2023, there can be no assurance that all costs incurred under the QIP rider during the open reconciliation years, which include 2016 through 2022, will be deemed recoverable by the ICC.

See Note 23,25, Regulatory Environment, in this report, and Note 26, Regulatory Environment, in our 20212022 Annual Report on Form 10-K for more information regarding recent and pending rate proceedings, orders, and investigations involving our utilities.

Petitions Before PSCW Regarding Third-Party Financed Distributed Energy Resources

In May 2022, two petitions were filed with the PSCW requesting a declaratory ruling that the owner of a third-party financed DER is not a "public utility" as defined under Wisconsin law and, therefore, is not subject to the PSCW’s jurisdiction under any statute or rule regulating public utilities. The parties that filed the petitions provide financing to their customers for installation of DERs (including solar panels and energy storage) on the customer’s property. A DER is connected to the host customer’s utility meter and is used for the customer’s energy needs. It may also be connected to the grid for distribution.

In July 2022, the PSCW found that the specific facts and circumstances merited the opening of a docket for each petition to consider whether to grant all or part of the requested declaratory ruling.

In December 2022, the PSCW granted one petitioner’s request for a declaratory ruling, finding that the owner of the third-party financed DER at issue in the petitioner’s brief is not a public utility under Wisconsin law. The ruling was limited to the specific facts and circumstances of the lease presented in that petition. A petition by the WUA to reopen or rehear the case expired without action by the PSCW. The WUA has filed an appeal which is pending consideration by the circuit court. The second petition is also currently being considered. Although the finding in the first petition was limited to the specific facts and circumstances of the lease presented in that petition, similar findings or a broader policy position could adversely impact our business operations.

Climate and Equitable Jobs Act

On September 15, 2021, the state of Illinois signed into law the Climate and Equitable Jobs Act. This new legislation includes, among other things, a path for Illinois to move towards 100% clean energy, expanded commitments to energy efficiency and renewable energy, additional consumer protections, and expanded ethics reform. The provisions in this legislation with the potential to have the most significant financial impact on PGL and NSG relate to the new consumer protection requirements.

Effective September 15, 2021, the new legislation prohibits utilities from charging customers a fee when they elect to pay for service with a credit card. Utilities are now required to incur these expenses and seek recovery through a rate proceeding or by establishing a recovery mechanism. In December 2021, the ICC approved the use of a TPTFA rider for PGL. The TPTFA rider allows PGL to recover

Table of Contents
the costs incurred for these third-party transaction fees, effective December 27, 2021. NSG recovers costs related to these third-party transaction fees through its base rates, effective September 15, 2021.

In accordance with the new legislation, effective January 1, 2023, natural gas utilities will alsoare no longer be allowed to charge late payment fees to certain low-income residential customers. We are currently evaluating the impact this legislation may have on our future results of operations.

Uyghur Forced Labor Prevention Act

The CBP issued a WRO in June 2021, applicable to certain silica-based products originating from the Xinjiang Uyghur Autonomous Region of China (Xinjiang), such as polysilicon, included in the manufacturing of solar panels. In June 2022, the WRO was superseded by the implementation of the UFLPA, which was signed into law by President Biden in December 2021. The UFLPA establishes a rebuttable presumption that any imports wholly or partially manufactured in Xinjiang are prohibited from entering the United

Table of Contents
States. While our suppliers were able to provide the CBP sufficient documentation to meet WRO compliance requirements, and we expect the same will be true for UFLPA purposes, we cannot currently predict what, if any, long-term impact the UFLPA will have on the overall supply of solar panels into the United States and the related long-term impact to timing and cost of solar projects included in our capital plan. However, we are seeing some delays in the release of solar panels by the CBP, which are having an impact on the timing and cost of certain of our solar projects.

United States Department of Commerce Complaints

In August 2021, a group of anonymous domestic solar manufacturers filed a petition (AD/CVD) with the DOC seeking to impose new tariffs on solar panels and cells imported from several countries, including Malaysia, Vietnam, and Thailand. The petitioners claimed that Chinese solar manufacturers are shifting products to these countries to avoid the tariffs required on products imported from China. In November 2021, the DOC rejected this petition. In denying the petition, the DOC cited the anonymous group’s refusal of the DOC’s request to provide more detail and identify its members due to concerns about retribution from the dominant Chinese solar industry.

In February 2022, a California based company filed a petition (AD/CVD)(Antidumping and Countervailing Duties) with the DOC seeking to impose new tariffs on solar panels and cells imported from multiple countries, including Malaysia, Vietnam, Thailand, and Cambodia. WhileThe petitioners claimed that Chinese solar manufacturers are shifting products to these countries to avoid the petition is similar to the one rejected by the DOC in November 2021, there are notable differences. The group added Cambodia to the petitiontariffs required on products imported from China and is requestingrequested that the DOC conduct a country-wide inquiry into each of the four countries. In MarchAfter investigation, on December 2, 2022, the DOC decided to actannounced its preliminary determination that certain companies are circumventing anti-dumping and countervailing duty orders on the February petitionsolar cells and investigate the claim.modules from China. A DOCfinal decision is currently expected by Januaryin the third quarter of 2023. If the DOC determines that the petition has merit,such circumvention is occurring it would be able to apply any final tariffs retroactively to November 4, 2021. If imposed, the new tariffs are expected tocould further disrupt the supply of solar modules to the United States, and could impact the cost and timing of our solar projects.

InTo address concerns raised about the adverse impact from the ongoing DOC complaint on the U.S. solar industry, in June 2022, the Biden Administration used its executive powers to issue a 24-month tariff moratorium on solar panels manufactured in Cambodia, Malaysia, Thailand, and Vietnam. The moratorium comes as a direct response to concerns raised aboutIn May 2023, the adverse impact fromBiden Administration vetoed legislation that would have repealed the ongoing DOC complaint on the U.S. solar industry.

Companies may still be subject to tariffs after the moratorium ends; however, U.S. companies will reportedly be exempt from any retroactive tariffs that previously could have applied. TheAdditionally, the Biden Administration also announced that it will invokeinvoked the Defense Production Act to accelerate the production of solar panels in the U.S. The Biden Administration's actions did not address whether WROs applied to panels under previous complaints would be affected.

Infrastructure Investment and Jobs Act

In November 2021, President Biden signed into law the Infrastructure Investment and Jobs Act, which provides for approximately $1.2 trillion of federal spending over the next five years, including approximately $85 billion for investments in power, utilities, and renewables infrastructure across the United States. We expect funding from this Act will support the work we are doing to reduce GHG emissions, increase EV charging, and strengthen and protect the energy grid. Funding in the Act should also help to expand emerging technologies, like hydrogen and carbon management, as we continue the transition to a clean energy future. We believe the Infrastructure Investment and Jobs Act will accelerate investment in projects that will help us meet our net zero emission goals to the benefit of our customers, the communities we serve, and our company.

Inflation Reduction Act

In August 2022, President Biden signed into law the IRA, which provides for $258 billion in energy-related provisions over a 10-year period. The provisions of the IRA are intended to, among other things, lower gasoline and electricity prices, incentivize domestic clean energy investment, manufacturing, and production, and promote reductions in carbon emissions. We believe that we and our customers can benefit from the IRA’s provisions that extend tax benefits for renewable technologies, increase or restore higher rates for PTCs, add an option to claim PTCs for solar projects, expand qualified ITC facilities to include standalone energy storage, and its provision to allow companies to transfer tax credits generated from renewable projects. The IRA also implements a 15% corporate alternative minimum tax and a 1% excise tax on stock repurchases. Although significant regulatory guidance is expected on the tax provisions in the IRA, we currently believe the provisions on alternative minimum tax and stock repurchases will not have a material impact on us. Overall, we believe the IRA will help reduce our cost of investing in projects that will support our commitment to reduce emissions and provide customers affordable, reliable, and clean energy over the longer term.

Return on Equity Incentive for Membership in a Transmission Organization

The FERC currently allows transmission utilities, including ATC, to increase their ROE by 50 basis points as an incentive for membership in a transmission organization, such as MISO. This incentive was established to stimulate infrastructure development

and to support the evolving electric grid. However, a Notice of Proposed Rulemaking was issued by the FERC on April 15, 2021 proposing to limit the 50 basis point increase in ROE to only be available to transmission utilities initially joining a transmission organization for the first three years of membership. If this proposal becomes a final rule, ATC would be required to submit, within

American Transmission Company Allowed Return on Equity ComplaintsComplaint

The ROE allowed by the FERC helps determine how much transmission owners, such as ATC, earn on their transmission assets as well as how much consumers pay for those assets. When a complaint was filed arguing the base ROE for MISO transmission owners, including ATC, was too high, the FERC started analyzing the base ROE for these transmission owners.

The base ROEs listed in the ROE complaint section below do not include the 50 basis point ROE incentive currently provided for membership in a transmission organization. See the Return on Equity Incentive for Membership in a Transmission Organization section above for more information on this incentive.

Return on Equity Complaint

In November 2013, a group of MISO industrial customers filed a complaint with the FERC asking that the FERC order a reduction to the base ROE used by MISO transmission owners, including ATC, from 12.2% to 9.15%. Due to this complaint, the FERC and the D.C. Circuit Court of Appeals issued the following orders and opinion. The refunds resulting from these orders and opinion are also described below.

Orders Issued by the FERC

September 2016 Order – On September 28, 2016, the FERC issued an order reducing the base ROE for MISO transmission owners to 10.32% for the period covered by the first complaint, November 12, 2013 through February 11, 2015 and September 28, 2016 going forward.

November 2019 Order – On November 21, 2019, the FERC issued ananother order (November 2019 Order) relatedafter directing MISO transmission owners and other stakeholders to provide briefs and comments on a proposed change to the methodology used to calculate thefor calculating base ROE for all MISO transmission owners, including ATC. Based onROE. In this order, the FERC expanded its base ROE methodology to include the capital-asset pricing model in addition to the discounted cash flow model to better reflect how investors make their investment decisions. The FERC also rejected the use of the risk premium model as part of its base ROE methodology in this order. The FERC's modified methodology further reduced the base ROE thatfor all MISO transmission owners, including ATC, is allowed to collect on a going-forward basis, as discussed below.9.88% for the period covered by the first complaint. In response to the FERC'sthis FERC decision, requests for the FERC to rehear the November 2019 Order in its entirety were filed by various parties.

May 2020 Order – On May 21, 2020, the FERC issued an order (May 2020 Order) that granted in part and denied in part the requests to rehear the November 2019 Order. In thethis May 2020 Order, the FERC made additional revisions to its base ROE methodology, including addingreinstating the use of the risk premium model. As discussed below, theThe additional revisions made by the FERC increased ATC's base ROE authorized in the November 2019 Order on a going-forward basis. Various parties filed requests to rehear certain parts of the May 2020 Order with the FERC, but the FERC issued an order in response to the rehearing requests during November 2020 (November 2020 Order) that confirmed the ROE authorized in the May 2020 Order. Petitions for review of the November 2019 Order, relevant parts of the May 2020 Order, and the November 2020 Order have also been filed with the D.C. Circuit Court of Appeals.

First Return on Equity Complaint

In November 2013, a group of MISO industrial customer organizations filed a complaint with the FERC requesting to reduce the base ROE used by MISO transmission owners, including ATC, from 12.2% to 9.15%. In September 2016, the FERC issued an order requiring MISO transmission owners to collect a reduced base ROE of 10.32%. This order also allowed the continued collection of any previously authorized ROE incentive adders. For MISO transmission owners, a 0.5% incentive adder was approved by the FERC in January 2015. The FERC then issued the November 2019 Order after directing MISO transmission owners and other stakeholders to provide briefs and comments on a proposed change to the methodology for calculating base ROE. The November 2019 Order further reduced the base ROE for all MISO transmission owners, including ATC, to 9.88%, effective as of September 28, 2016 and prospectively. The November 2019 Order also continued to allow the collection of previously authorized ROE incentive adders, but ATC's ROE incentive adder of 0.5% only applies to revenues collected after January 6, 2015. In response to the rehearing requests filed related to the November 2019 Order, the FERC issued another order in May 2020. This May 2020 Order increased the base ROE for all MISO transmission owners, including ATC, from the 9.88% authorized in the November 2019 Order to 10.02%, effective as for the period covered by the first complaint. Various parties then filed requests to rehear certain parts of September 28, 2016 and prospectively. Thethe May 2020 Order also allowedwith the continued collection of previously authorized ROE incentive adders. However, ATC's 0.5% ROE incentive adder may be eliminated going forward, as discussed above.FERC.

November 2020 Order – In response to the rehearing requests filed concerning certain parts of the May 2020 Order, the FERC issued an order in November 2020 that confirmed the ROE previously authorized in its May 2020 Order.

Refunds – Due to the base ROE changes resulting from these FERC orders, ATC was required to provide refunds, with interest, for the 15-month refund period from November 12, 2013 through February 11, 2015 and for the period from September 28, 2016 through November 19, 2020. In January 2022, ATC completed providing WE, WPS, and WPSUMERC with the net refunds related to the transmission costs they paid during the two refund periods. Theseperiod covered by the first complaint. The refunds were applied to WE's and WPS's PSCW-approved escrow accounting for transmission expense.

Environmental Matters

Manlove Field Matter

In September 2017, the Illinois Department of Natural Resources, Office of Oillawsuit and Gas Resource Management, issued a VN to PGL related to a leak of natural gas from a well located at the PGL Manlove Gas Storage Field in December 2016. PGL quickly shut down and permanently plugged the well to contain the leak after it was discovered. The leak resulted in the migration of natural gas from the well to the Mahomet Aquifer located in central Illinois and impacted residential freshwater wells. PGL has been working with residents potentially impacted by the natural gas leak and the Illinois state agencies, to investigate and remediate the impacts of the natural gas leak to the Mahomet Aquifer. In October 2017, the Illinois AG filed a complaint against PGL alleging certain violations of the Illinois Environmental Protection Act and the Oil and Gas Act. PGL entered into an Agreed Interim Order with the State of Illinois in October 2017 and a First Amended Agreed Interim Order in September 2019 whereby PGL agreed, among other things, to continue actions it was already undertaking proactively, including the submittal of a GMZ application to the IEPA. A supplemental filing was sent to the IEPA in December 2019. In September 2020, the IEPA sent PGL a letter conditionally approving the GMZ application. PGL has taken steps to implement the requirements of the approved GMZ project.

In addition, in December 2017, the IEPA issued a VN to PGL alleging the same violations as the AG. Lastly, in January 2018, the IEPA issued a VN alleging certain violations of Illinois air emission rules arising from the construction and operation of flaring equipment at the leak site. Both of the IEPA VN matters have been referred to the AG for enforcement.

PGL and the AG agreed to the terms of a final consent order, which was entered by the court in June 2022. PGL has agreed to pay an aggregate of $575,000, including a civil penalty of $175,000. The consent order also requires PGL to complete the GMZ andintends to continue to provide methane detection devices, bottled water and gas/water separators to affected homeowners, as defined in the final consent order, until certain conditions are satisfied.do so.
